2,4-Diaminotoluene, also known as 2,4-TDA and identified by its CAS number 95-80-7, is a fundamental aromatic amine that plays a crucial role in various industrial chemical syntheses. Understanding its properties, common production methods, and the best practices for sourcing is vital for procurement specialists and research scientists alike.

Chemically, 2,4-Diaminotoluene has the molecular formula C7H10N2 and a molecular weight of approximately 122.17 g/mol. It typically appears as light brown crystals and possesses a melting point in the range of 97-99 °C. Its boiling point is around 283-285 °C, and it exhibits moderate solubility in water. While stable under normal storage conditions, it requires careful handling due to its chemical nature. As a key intermediate, its purity is of utmost importance, with industrial grades often specified at a minimum of 98%.

The primary synthesis route for 2,4-Diaminotoluene involves the catalytic hydrogenation of 2,4-dinitrotoluene. This method is widely adopted by chemical manufacturers due to its efficiency and the availability of the starting material. The quality of the catalyst and precise control over reaction parameters, such as temperature and pressure, are critical for achieving high yields and purity. For companies looking to buy 2,4-diaminotoluene, understanding the synthesis process can provide insights into potential impurities and quality variations between different suppliers.

When it comes to sourcing 2,4-TDA, identifying a reliable 2,4-TDA manufacturer is the first step. Leading suppliers, often found in regions like China, offer competitive 2,4-diaminotoluene prices and can manage large-scale orders. Essential documentation, including Certificates of Analysis (COA) and Safety Data Sheets (SDS), should always be requested to verify purity, confirm physical and chemical properties, and ensure compliance with safety regulations. For many applications, such as the production of toluene diisocyanate (TDI) or as a dye intermediate, consistent quality is non-negotiable.

The utility of 2,4-Diaminotoluene extends beyond TDI; it is also used in the synthesis of various dyes and in hair coloring formulations, highlighting its broad applicability. For any organization seeking to procure this chemical, it is advisable to engage with experienced 2,4-diaminotoluene suppliers who can provide technical support and ensure a stable supply chain. A well-informed procurement strategy for 2,4-TDA is key to successful industrial operations.
