For professionals in the chemical and manufacturing sectors, the quality of raw materials directly dictates the performance and integrity of the final product. 2,4-Diaminotoluene (2,4-TDA), a compound with CAS number 95-80-7, is no exception. Its primary role as an intermediate in the production of toluene diisocyanate (TDI) and its applications in the dye industry demand stringent quality controls.

When you decide to buy 2,4-diaminotoluene, several key parameters should be at the forefront of your evaluation. The most critical is purity. Industrial standards often require a minimum purity of 98%, typically verified through methods like titration or gas chromatography (GC) analysis, as indicated by many 2,4-TDA manufacturers. A higher purity level ensures more efficient reactions in TDI synthesis and consistent coloring properties in dye applications, minimizing batch-to-batch variations.

The appearance of the product is another important indicator. High-quality 2,4-Diaminotoluene is usually described as light brown crystals. Deviations from this description, such as a darker color or the presence of significant foreign matter, could suggest contamination or degradation. Physical properties like melting point, which typically falls between 97-99 °C, also serve as a benchmark for quality. Any significant deviation might warrant further investigation into the batch’s integrity.

For buyers, securing a reliable supply chain is as vital as product quality. Partnering with a reputable 2,4-diaminotoluene supplier, particularly one with experience in exporting from China, ensures access to necessary documentation. This includes Certificates of Analysis (COA) for each batch, confirming its adherence to specifications, and Safety Data Sheets (SDS), which provide crucial handling and safety information. These documents are indispensable for regulatory compliance and for your internal safety protocols.

When comparing 2,4-diaminotoluene prices, it's essential to consider the total value proposition, which includes not only the per-kilogram cost but also the guaranteed quality, reliability of supply, and responsive customer service. A supplier’s commitment to quality assurance is a strong indicator of their trustworthiness. Therefore, prioritizing suppliers who transparently share their quality control processes and provide comprehensive product data is a strategic approach to procuring this essential chemical intermediate.
