For professionals in chemical procurement and R&D, a thorough understanding of key industrial chemicals is essential for making informed purchasing decisions. Basic Chrome Sulfate (BCS), identified by CAS number 72993-54-5, is one such vital compound, predominantly utilized in the leather industry. This article delves into its core properties, diverse applications, and provides insights into sourcing this chemical effectively, particularly from competitive global markets like China.

Basic Chrome Sulfate is an inorganic chemical compound, typically presented as a fine green powder. Its molecular formula is often represented as Cr(OH)SO4, and it is known for its high tanning capabilities. A critical parameter for BCS is its basicity, which influences its reactivity and penetration into materials like leather. Manufacturers commonly specify basicity percentages (e.g., 33±1%) and chromium oxide content (e.g., 25±1%) to denote product quality and grade. Its solubility in water makes it convenient for use in aqueous processing solutions.

The primary and most significant application of Basic Chrome Sulfate is as a tanning agent in the leather industry. It plays a pivotal role in the chrome tanning process, which transforms raw animal hides and skins into stable, durable leather. The chemical effectively binds to the protein structure of collagen, increasing its resistance to thermal degradation, microbial action, and mechanical wear. This process is fundamental to producing high-quality leather suitable for a wide range of consumer and industrial goods. For tanneries, securing a consistent supply of quality BCS from a reliable manufacturer is a strategic priority.

Beyond leather, BCS also serves as a valuable mordant in the textile and dyeing sectors. Mordants help to fix dyes onto fabrics, improving the color fastness and vibrancy. This application showcases the chemical's utility in enhancing the quality and durability of dyed materials.

When seeking to purchase Basic Chrome Sulfate, buyers often look towards manufacturers in China due to the competitive pricing and extensive production capabilities available. It is crucial to establish a direct relationship with a reputable supplier that can provide detailed product specifications, safety data sheets (SDS), and certificates of analysis (CoA). Understanding the company's export experience, quality control measures, and packaging options (e.g., 25kg bags) will ensure a smooth procurement process.

For businesses that require this essential chemical, reaching out to potential suppliers for quotes and samples is the next step. Evaluating the product's performance in your specific application, alongside the supplier's reliability and customer service, will lead to the best partnership. Investing in high-quality Basic Chrome Sulfate is an investment in the quality and longevity of your end products.
