Clofibrate

About Clofibrate

Clofibrate is an API reference standard carrying the CAS registry number 637-07-0. Its molecular formula is C12H15ClO3 and its molecular weight is 242.7 g/mol. The IUPAC name is ethyl 2-(4-chlorophenoxy)-2-methylpropanoate. It is also known as Ethyl clofibrate or Atromid-S.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. It is used across pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
