Tiamulin EP Impurity A

About Tiamulin EP Impurity A

Tiamulin EP Impurity A is a pharmacopeial impurity of Tiamulin carrying the CAS registry number 6040-37-5. Its molecular formula is C20H32O3 and its molecular weight is 320.5 g/mol. Its systematic (IUPAC) name is (1S,2R,3S,4S,6R,7R,8R,14R)-4-ethenyl-3,6-dihydroxy-2,4,7,14-tetramethyltricyclo[5.4.3.01,8]tetradecan-9-one. It is also known as Mutilin or Tiamulin Fumarate - Impurity A.

The product is provided 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 “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Pharmaceutical QC and development laboratories use this impurity standard of Tiamulin to develop and validate HPLC methods, to set specification limits and to document impurity profiles in ANDA and DMF submissions. 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.
