For procurement managers in the chemical and pharmaceutical industries, sourcing high-quality raw materials is paramount to production success. One such critical intermediate is 3,4-Diaminotoluene, identified by its CAS number 496-72-0. This compound plays a vital role as a building block in the synthesis of a wide array of products, most notably in the pharmaceutical sector and in the creation of various dyes. Understanding its properties and procurement channels can significantly streamline your supply chain.

Understanding 3,4-Diaminotoluene (CAS 496-72-0)

3,4-Diaminotoluene, also known by synonyms such as 4-Methyl-1,2-benzenediamine or Tolylene-3,4-diamine, is an aromatic amine. Its molecular formula is C7H10N2, with a molecular weight of approximately 122.17. Typically appearing as a white crystal powder or crystalline chunks, it has a melting point in the range of 87-90°C. The key to its utility lies in its diamine functionality, which makes it a versatile reactant in organic synthesis. For procurement professionals, identifying a reliable manufacturer of 3,4-diaminotoluene who can consistently deliver the required purity levels (often 99% min) is essential.

Key Applications Driving Demand

The demand for 3,4-Diaminotoluene is primarily driven by its critical applications:

  • Pharmaceutical Intermediates: It serves as a fundamental intermediate in the synthesis of various pharmaceutical drugs. R&D scientists often look to buy 3,4-diaminotoluene for creating complex molecular structures that form the basis of active pharmaceutical ingredients (APIs). Ensuring a consistent supply of this intermediate is crucial for pharmaceutical production timelines.
  • Dye Manufacturing: Historically and presently, aromatic diamines like 3,4-Diaminotoluene are indispensable in the production of dyes. They are used in the synthesis of azo dyes and other colorants for textiles, inks, and pigments. The color fastness and vibrancy of the final dye often depend on the purity of the intermediate used.
  • Organic Synthesis: Beyond these primary uses, it is a valuable reagent in broader organic synthesis, enabling the creation of heterocyclic compounds and specialty chemicals used in various industrial applications.

Navigating the Supply Chain: Finding a Trusted Supplier

For businesses looking to buy 3,4-diaminotoluene, especially in bulk, identifying a reputable 3,4-diaminotoluene supplier in China is often the most strategic approach. Chinese manufacturers frequently offer competitive 3,4-diaminotoluene price points due to economies of scale and established production capabilities. When evaluating potential suppliers, consider the following:

  • Purity Specifications: Confirm that the supplier can meet your required purity standards (e.g., ≥99.0%).
  • Certifications and Quality Control: Look for evidence of robust quality control measures.
  • Packaging and Delivery: Ensure they offer suitable packaging options (e.g., 25kg bags or drums) and reliable shipping to your location.
  • Customer Service and Technical Support: A supplier that can provide technical data (like MSDS and COA) and respond promptly to inquiries is invaluable.
  • Order Flexibility: While bulk purchasing is common, understanding their capacity for smaller R&D orders can also be beneficial.

Partnering with a dependable CAS 496-72-0 manufacturer means securing a stable supply of this essential chemical. By focusing on quality, reliability, and competitive pricing, procurement managers can ensure their operations are well-supported, driving innovation and efficiency in their respective industries.
