3,4-Xylidine, chemically known as 3,4-Dimethylaniline and identified by CAS number 95-64-7, is a versatile aromatic amine with a distinct set of physical and chemical properties. As a white crystalline powder with a melting point around 49-51°C, it is a solid at room temperature, distinguishing it from some other aniline derivatives. Its molecular formula is C8H11N, with a molecular weight of approximately 121.18 g/mol. These characteristics, along with its chemical reactivity, make it a valuable compound for various industrial syntheses.

The utility of 3,4-Xylidine spans several key sectors. Primarily, it is recognized as a critical intermediate in the agrochemical industry, serving as a precursor for the herbicide Pendimethalin. This application alone drives significant global demand, as Pendimethalin is widely employed to control weeds in a multitude of crops. The effectiveness of Pendimethalin is directly linked to the quality of its precursors, emphasizing the need for high-purity 3,4-Xylidine, typically with an assay of ≥99.0%.

In addition to its agricultural applications, 3,4-Xylidine is also utilized in the pharmaceutical industry as an intermediate for Vitamin B2 (Riboflavin) synthesis. Vitamin B2 is essential for various metabolic processes in the human body, and its reliable production relies on efficient synthesis pathways involving intermediates like 3,4-Xylidine. Furthermore, this compound can also serve as a dye intermediate, demonstrating its broader applicability in chemical manufacturing.

For businesses looking to procure 3,4-Xylidine, understanding the sourcing landscape, particularly from China, is advantageous. Chinese chemical manufacturers offer competitive pricing and a wide range of products. When selecting a supplier, it is essential to look for companies that provide detailed product specifications, such as density (around 1.076 g/cm³), boiling point (approx. 226-228°C), and flash point (around 98.3°C), along with guaranteed assay percentages. NINGBO INNO PHARMCHEM CO.,LTD., for example, is a well-regarded supplier known for its commitment to quality and its comprehensive product offerings.

When initiating a purchase, it is advisable for procurement managers to request comprehensive quotes, inquire about minimum order quantities (MOQs), and discuss packaging options, which are often available in 25kg drums or can be customized. The ability to buy directly from a manufacturer ensures a streamlined supply chain and can lead to cost efficiencies. For R&D scientists or formulation specialists, understanding the chemical properties and availability of 3,4-Xylidine will facilitate their project planning and execution. Therefore, identifying a trustworthy manufacturer and supplier for 3,4-Xylidine, especially from a major chemical production hub like China, is a critical step for many industries.
