About Clarithromycin EP impurity K

Clarithromycin EP impurity K is a pharmacopeial impurity of Clarithromycin carrying the CAS registry number 127157-35-1. Its molecular formula is C30H51NO8 and its molecular weight is 553.7 g/mol. It is also known as Clarithromycin USP Impurity K or Clarithromycin - Impurity K.

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. Handle it with standard laboratory precautions and appropriate personal protective equipment.

As a characterised impurity of Clarithromycin, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. Buyers come mainly from 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.
