3,4-Dimethylaniline, a member of the aniline family, is an aromatic amine characterized by the presence of two methyl groups attached to the benzene ring at the 3 and 4 positions. Its Chemical Abstracts Service (CAS) registry number is 95-64-7, and it is also commonly referred to as 3,4-Xylidine or 3,4-Dimethylbenzenamine. This compound typically presents as a white crystalline powder, with a melting point in the range of 49-51°C, indicating it is a solid under standard room conditions. Its molecular formula is C8H11N, and it has a molecular weight of approximately 121.18 g/mol. Key physical properties include a density of about 1.076 g/cm³ and a boiling point around 226-228°C at atmospheric pressure. Its solubility in water is limited (<1 g/L at 24°C), but it is soluble in many organic solvents like methanol.

The industrial utility of 3,4-Dimethylaniline is multifaceted, stemming from its reactive amine group and the influence of the methyl substituents on the aromatic ring. Its most prominent application is as a critical intermediate in the synthesis of the herbicide Pendimethalin. Pendimethalin is a widely utilized pre-emergence herbicide effective against a broad spectrum of annual grasses and certain broadleaf weeds, making 3,4-Dimethylaniline a key component for agrochemical manufacturers. Companies seeking to buy this chemical for herbicide production prioritize its purity, often specified as ≥99.0% assay, to ensure efficient synthesis and high-quality end products.

Furthermore, 3,4-Dimethylaniline serves as an important intermediate in the pharmaceutical industry, notably in the production of Vitamin B2 (Riboflavin). Vitamin B2 is essential for human health and metabolism, and its synthesis pathways often incorporate this aniline derivative. This dual application across agrochemicals and pharmaceuticals underscores the compound's industrial significance. It also finds use as an intermediate in the synthesis of certain dyes, adding to its versatility.

For businesses looking to procure 3,4-Dimethylaniline, understanding the market and reliable suppliers is crucial. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. provide this chemical with high purity and in various packaging options, such as 25kg drums, to meet diverse industrial needs. When considering a purchase, buyers often look for competitive pricing, consistent product quality, and reliable supply chain management. Direct inquiries to manufacturers for price quotes and technical specifications are recommended to ensure optimal sourcing. The ability to buy in bulk from a reputable producer ensures cost-effectiveness and supply chain stability, essential for continuous manufacturing operations.

In summary, 3,4-Dimethylaniline is a valuable organic intermediate with well-defined physical and chemical properties. Its established applications in the synthesis of herbicides like Pendimethalin and pharmaceuticals like Vitamin B2 make it a sought-after chemical. Sourcing this compound from reliable manufacturers, particularly those in China, provides access to high-purity material at competitive prices, supporting critical industrial processes.
