Red Sun’s 3,5-dimethylpyridine (CAS 591-22-0, C₇H₉N) serves as a foundational intermediate within the pyridine derivatives family, delivering exceptional value to agrochemical, pharmaceutical, and specialized chemical manufacturing sectors. Presenting as a clear, colorless to pale yellow liquid, this compound emits a distinct, pungent pyridine-like odor characteristic of its molecular structure. The presence of two methyl groups at the 3 and 5 positions creates specific steric hindrance and mild basicity (pKa ~6.15), making it an indispensable building block for synthesizing complex, advanced compounds required in modern industrial applications.
With a guaranteed purity of ≥99.0% and rigorously verified chemical stability, this industrial-grade 3,5-dimethylpyridine guarantees consistent, reproducible performance across large-scale production environments. It is fully miscible with ethanol, ether, and most standard organic solvents, while maintaining moderate solubility in water, allowing formulation engineers significant flexibility. Its proven reliability and strict impurity control make it a preferred raw material for formulating high-efficiency pesticides, synthesizing critical pharmaceutical active ingredients (APIs), and developing specialized surfactants that must pass stringent global regulatory audits.

The structurally unique properties of 3,5-Dimethylpyridine allow it to function efficiently across multiple demanding industrial sectors. Its specific steric profile and basicity enable it to act not only as a structural backbone but also as a highly effective acid scavenger and catalyst in complex synthesis pathways. The following sections detail its primary operational roles and performance metrics.
Within agricultural chemical production, this compound is vital for synthesizing potent herbicides, including diquat and paraquat derivatives. It equally supports the large-scale manufacturing of advanced insecticides such as chlorpyrifos and chlorantraniliprole. By utilizing a ≥99.0% purity intermediate, formulation facilities experience fewer side reactions, resulting in higher overall yields, less waste, and greater stability in the final agrochemical products.
In the heavily regulated pharmaceutical sector, 3,5-dimethylpyridine acts as a critical precursor for synthesizing vitamin B3 (niacin) and niacinamide. Its exceptionally low moisture content (≤0.20%) and the complete absence of detectable 2,3- or 2,4,5-isomers ensure that API manufacturers can maintain strict compliance with pharmacopeia standards. This level of purity prevents the formation of unwanted by-products, streamlining downstream purification processes for pharmaceuticals, food additives, and cosmetic ingredients.
Beyond specific end-products, this compound is widely utilized to synthesize secondary intermediates like 2-amino-3-methylpyridine and 2-chloro-N-(2-chloro-4-methylpyridin-3-yl)nicotinamide. Due to its unique molecular geometry, it serves as an excellent steric base and acid scavenger in various condensation and nucleophilic substitution reactions. Furthermore, it functions as a specialized solvent component, facilitating reactions that require a mildly basic, highly stable organic environment.

The chemical flexibility of 3,5-dimethylpyridine allows it to adapt to diverse manufacturing protocols. From acting as a core reactive intermediate in pesticide synthesis to serving as a catalytic agent in specialized polymer production, its multi-functional nature reduces the need to source multiple distinct chemicals, thereby optimizing inventory management for multi-line production facilities.
Due to its chemical nature, 3,5-Dimethylpyridine requires strict adherence to controlled storage protocols, precise labeling, and the use of appropriate personal protective equipment (PPE). The following guidelines outline the critical safety and handling requirements to protect facility personnel and ensure environmental compliance.
The product packaging is clearly marked with GHS02 (Flammable), GHS05 (Corrosive), and GHS06 (Toxic) hazard symbols. In accordance with international chemical classification standards, the designated signal word is "Danger," alerting handlers to the necessary precautions before interacting with the containers.
This compound is assigned specific hazard codes: H226 (Flammable liquid and vapor), H301+H331 (Toxic if swallowed or inhaled), H312 (Harmful in contact with skin), and H314 (Causes severe skin burns and eye damage). Facility managers must integrate these warnings into their internal risk assessment and training programs.
Operational safety is guided by statements such as P261 (Avoid breathing dust/fume/gas/mist/vapors/spray), P280 (Wear protective gloves/protective clothing/eye protection/face protection), and P301+P310+P330 (IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician; Rinse mouth). These directives form the baseline for emergency response protocols on the factory floor.
To prevent exposure to its pungent vapors and corrosive liquid form, workers must utilize chemical-splash eyeshields, full faceshields, and heavy-duty chemical-resistant gloves. For environments where vapor concentrations may exceed safe thresholds, full-face respirators equipped with ABEK combination filters are strictly recommended.
Under European directives, the risk codes R10 (Flammable) and R20/21/22 (Harmful by inhalation, in contact with skin, and if swallowed) apply. Corresponding safety codes include S16 (Keep away from sources of ignition), S26 (In case of contact with eyes, rinse immediately), and S36/37 (Wear suitable protective clothing and gloves).
For global transit, the product is classified under UN1993/PG3, falling within hazard class 3 and packaging group III. To accommodate different scales of industrial procurement, it is securely packaged in robust 200L steel drums or 1000L IBC totes, ensuring maximum physical integrity and leak prevention during international shipping.
According to German environmental standards, the WGK classification is 3, indicating a severe hazard to water sources. Facilities must implement secondary containment systems and strict spill-response measures to prevent any accidental release into municipal drains or natural waterways.
To maintain its ≥99.0% purity, the liquid must be stored in tightly sealed containers under a dry, inert atmosphere (such as nitrogen). Storage facilities should maintain cool, ambient temperatures, strictly avoiding direct sunlight, moisture, or heat sources. Under these optimal conditions, the product offers a highly stable shelf life of 12 to 24 months.
This compound is highly miscible with most common organic solvents, including ethanol, ether, and acetone, which facilitates its use in diverse organic synthesis reactions. While it is soluble in water, its aqueous solubility is moderate, a factor that formulation engineers utilize when designing phase-separation and extraction processes.
The presence of two methyl groups at the 3 and 5 positions provides specific steric hindrance around the nitrogen atom. This unique geometry allows it to act as an effective, mild steric base and an excellent acid scavenger without interfering with sensitive nucleophilic substitutions, thereby improving reaction selectivity and overall yield.
To streamline procurement and regulatory audits, every bulk shipment is accompanied by a comprehensive Certificate of Analysis (COA) verifying the ≥99.0% purity and absence of isomers. Additionally, updated Material Safety Data Sheets (MSDS) and relevant transport compliance certificates are provided to ensure seamless facility integration and safety compliance.
