Nilutamide EP Impurity D

About Nilutamide EP Impurity D

Nilutamide EP Impurity D is a pharmacopeial impurity standard carrying the CAS registry number 6167-23-3. Formula C15H8F6N4O5, molecular weight 438.24 g/mol. Systematically, it is named 1,3-bis[4-nitro-3-(trifluoromethyl)phenyl]urea. Common synonyms include Nilutamide - Impurity D and Nilutamide EP Impurity D (Free Base).

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

This the parent drug substance impurity supports analytical method development and validation (AMV), batch release testing and the impurity sections of ANDA and DMF filings. Typical end-use sectors are 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.
