In the complex landscape of chemical procurement, precise identification of substances is paramount. The Chemical Abstracts Service (CAS) registry number is the universal standard for uniquely identifying chemical substances. For businesses involved in chemical supply, understanding the importance and proper use of CAS numbers, such as for S(-)2-Chloropropionic Acid (CAS 29617-66-1), is crucial for ensuring accurate ordering, regulatory compliance, and efficient supply chain management. This guide explains why CAS numbers are indispensable tools for procurement professionals and R&D scientists.

What is a CAS Number and Why is it Essential?

A CAS number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. It consists of three parts, separated by hyphens, serving as an unambiguous identifier regardless of chemical name variations, synonyms, or trade names. For a compound like S(-)2-Chloropropionic Acid, using its CAS number, 29617-66-1, eliminates confusion. It ensures that whether a buyer searches for 'S(-)2-Chloropropionic Acid,' 'L-α-Chloropropionic acid,' or any other synonym, they are consistently referencing the same specific chemical entity.

Streamlining Procurement with CAS Numbers

For procurement managers, relying on CAS numbers simplifies the sourcing process. When you need to buy S(-)2-Chloropropionic Acid, specifying CAS 29617-66-1 ensures that suppliers understand exactly which compound you require. This precision is vital for:

  • Accurate Ordering: Prevents costly errors from misidentification of chemicals.
  • Supplier Verification: Allows for quick cross-referencing of product catalogs from various manufacturers.
  • Regulatory Compliance: Essential for safety data sheets (SDS), shipping documentation, and import/export regulations.
  • Database Management: Simplifies inventory tracking and chemical management systems.

Engaging with a chemical manufacturer or supplier often involves requesting quotes based on CAS numbers. For example, when inquiring about S(-)2-Chloropropionic Acid, stating 'CAS 29617-66-1' along with your required quantity and purity immediately clarifies your need.

Sourcing S(-)2-Chloropropionic Acid with Confidence

When sourcing S(-)2-Chloropropionic Acid, always confirm the CAS number provided by the supplier matches your requirements. Reputable chemical suppliers, such as those specializing in fine chemicals and pharmaceutical intermediates, will prominently display CAS numbers for all their products. They understand its critical role in B2B transactions. By focusing on suppliers who clearly identify their products by CAS number and provide comprehensive supporting documentation, you can confidently purchase the chemicals necessary for your manufacturing and research needs.

In conclusion, CAS numbers are foundational to accurate and efficient chemical procurement. Utilizing the CAS number for S(-)2-Chloropropionic Acid (29617-66-1) ensures clarity and precision in your dealings with chemical manufacturers and suppliers. This systematic approach is key to building a robust and reliable supply chain for essential chemical intermediates.
