In the highly regulated and precise world of chemical procurement, particularly within the pharmaceutical industry, the Chemical Abstracts Service (CAS) Registry Number is an indispensable identifier. For buyers and researchers, understanding the significance of a CAS number ensures accuracy, traceability, and safety. This article highlights the importance of CAS numbers using Cyclopropyl-2-fluoro Benzyl Ketone (CAS 150322-73-9), a critical intermediate, as a case study.

What is a CAS Number and Why is it Crucial?

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, with the first part ranging from one to seven digits, the second part from two to eight digits, and the third part a single digit, which serves as a check digit. The CAS Registry is maintained by the Chemical Abstracts Service, a division of the American Chemical Society.

The primary function of a CAS number is to provide an unambiguous way to identify a specific chemical substance, regardless of its common name, trade name, or systematic name. This is particularly important for several reasons:

  • Uniqueness: It eliminates confusion caused by synonyms or differing nomenclature systems used in various regions or industries.
  • Global Recognition: CAS numbers are universally recognized and used by chemists, regulatory agencies, and businesses worldwide.
  • Regulatory Compliance: Government agencies, such as the EPA and FDA, rely on CAS numbers for tracking, regulating, and reporting on chemical substances.
  • Facilitating Trade: Clear identification through CAS numbers streamlines international trade by ensuring that all parties are referring to the same substance.

Cyclopropyl-2-fluoro Benzyl Ketone (CAS 150322-73-9): A Key Identifier

For pharmaceutical manufacturers and researchers, correctly identifying intermediates is non-negotiable. Cyclopropyl-2-fluoro Benzyl Ketone, with its CAS number 150322-73-9, is a prime example. This number guarantees that when you buy this compound, you are receiving the exact chemical structure required for the synthesis of Prasugrel hydrochloride, a complex API. Without the CAS number, you risk misidentification, which could lead to incorrect synthesis, product failure, or regulatory issues.
