Understanding Chloromethyl Isopropyl Carbonate (CAS No. 35180-01-9): A Key Intermediate in Pharmaceutical Synthesis

The chemical industry is the cornerstone of modern science and technology, supplying essential compounds for industries ranging from agriculture to electronics. One niche but critical segment of this industry is the manufacturing of pharmaceutical intermediates—chemical compounds used in the synthesis of active pharmaceutical ingredients (APIs). One such intermediate that plays a pivotal role in antiviral drug synthesis is Chloromethyl Isopropyl Carbonate, identified by its Chemical Abstracts Service (CAS) number: 35180-01-9.

What is Chloromethyl Isopropyl Carbonate?

Chloromethyl Isopropyl Carbonate (CMIC) is an organic compound that exists as a colorless to pale yellow liquid. It belongs to the family of chloroformates, a group of chemicals often used in organic synthesis due to their reactivity with amines, alcohols, and acids. CMIC, in particular, is prized for its role as a reagent and intermediate in the pharmaceutical sector.

Its molecular formula is C5H9ClO3, and it has a molar mass of approximately 152.58 g/mol. This unique composition imparts specific reactivity that is highly valuable in drug synthesis.
