About Valsartan Methyl Ester
Valsartan Methyl Ester is a metabolite or degradation product of Valsartan carrying the CAS registry number 137863-17-3. With the molecular formula C25H31N5O3, it has a molar mass of 449.5 g/mol. The IUPAC name is methyl (2S)-3-methyl-2-[pentanoyl-[[4-[2-(2H-tetrazol-5-yl)phenyl]phenyl]methyl]amino]butanoate.
It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.
It is used in metabolite identification, stability-indicating method development and impurity profiling of Valsartan, as well as in QC testing and ANDA/DMF documentation. 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.
