In the intricate world of chemical supply chains, CAS (Chemical Abstracts Service) registry numbers serve as unique identifiers for chemical substances. These numbers are indispensable for unambiguous identification and are critical for regulatory compliance, scientific literature searching, and commercial transactions. For pharmaceutical manufacturers, understanding and reliably sourcing compounds with specific CAS numbers is fundamental to their operations.

The compound identified by CAS number 188416-35-5, namely (2R,3S/2S,3R)-3-(4-Chloro-5-fluoro-6-pyrimidinyl)-2-(2,4-difluorophenyl)butan-2-ol hydrochloride, is a prime example of a vital intermediate whose accurate identification is paramount. This specific chemical entity is a crucial precursor in the synthesis pathway of Voriconazole, a powerful antifungal agent used to treat serious fungal infections. The efficacy of Voriconazole relies heavily on the stereochemistry and purity of this intermediate.
