In the competitive landscape of chemical manufacturing, understanding the synthesis and quality control of key intermediates is paramount. 4-Nitro-2-Sulfoaniline (CAS 96-75-3), a vital compound used extensively in dye and pharmaceutical industries, exemplifies the importance of precise production and rigorous quality assurance. This article delves into the synthesis pathways and the critical aspects of ensuring high purity for this versatile chemical.

Synthesis Pathways for 4-Nitro-2-Sulfoaniline

The production of 4-Nitro-2-Sulfoaniline typically involves controlled chemical reactions that introduce the nitro and sulfonic acid groups onto an aniline derivative. One common industrial approach involves the nitration of 2-aminobenzenesulfonic acid. This process requires careful management of reaction conditions, including temperature and reagent concentration, to ensure regioselectivity, meaning the nitro group attaches to the correct position on the benzene ring, specifically at the para position relative to the amino group and ortho to the sulfonic acid group.

Industrial synthesis often employs scaled-up processes that prioritize efficiency, yield, and cost-effectiveness while adhering to environmental regulations. These sophisticated manufacturing methods ensure that the product is produced in bulk to meet market demand. As a reputable manufacturer, we leverage advanced synthesis techniques to deliver 4-Nitro-2-Sulfoaniline that consistently meets high purity standards.

The Importance of Purity and Typical Properties

The effectiveness of 4-Nitro-2-Sulfoaniline as a dye intermediate or pharmaceutical building block is heavily dependent on its purity. Typically supplied with an assay of 98% minimum, and often achieving over 99.15%, this compound's clarity is vital. Impurities can lead to undesirable side reactions, reduced color vibrancy in dyes, or compromise the efficacy and safety of pharmaceutical products.

Key properties include its appearance as a light white crystal, a molecular weight of 218.19 g/mol, and a melting point around 196°C. These characteristics, along with its chemical formula C6H6N2O5S, are standard identifiers for quality assessment. For businesses looking to buy 4-Nitro-2-Sulfoaniline, verifying these specifications from their supplier is a crucial step in ensuring product integrity.
