For procurement professionals in the chemical industry, securing a reliable supply of high-quality intermediates is crucial for maintaining production schedules and product quality. Among these essential compounds is 5-Amino-2-[(4-aminophenyl)amino]benzenesulfonic acid, identified by CAS number 119-70-0 and often referred to as FC Acid. This chemical intermediate is a vital component in the synthesis of various direct dyes, making its availability and quality directly impactful on the textile, paper, and leather industries.

When evaluating suppliers for CAS 119-70-0, several factors come into play. Firstly, the purity and assay of the product are paramount. A minimum assay of 98% is typically expected for FC Acid to ensure consistent performance in dye synthesis, particularly for producing vibrant colors in dyes like Direct Black 22 and Direct Blue 175. Secondly, understanding the manufacturer's production capacity and their commitment to quality control is essential. Many global buyers turn to manufacturers in China due to competitive pricing and established production capabilities. NINGBO INNO PHARMCHEM CO.,LTD. facilitates access to such reliable manufacturers, ensuring you can purchase this intermediate with confidence.

The physical characteristics of FC Acid, such as its yellow crystal appearance, provide initial indicators of quality. However, comprehensive technical specifications and a responsive supplier are equally important. Buyers often search for terms like 'buy 119-70-0 online', 'FC Acid price', or 'dye intermediate supplier China' to identify potential partners. It's crucial to inquire about packaging (typically 25 kg drums) and shipping options, whether by air, sea, or courier, to ensure timely delivery for your manufacturing needs. Developing a relationship with a trusted manufacturer or a specialized chemical distributor ensures a steady stream of this critical raw material.
