About Triamterene EP Impurity A

Triamterene EP Impurity A (CAS 1006-23-1) is a nitrosamine impurity of Triamterene offered by Vaqora Chemicals. Formula C4H6N6O, molecular weight 154.13 g/mol. Its systematic (IUPAC) name is 5-nitrosopyrimidine-2,4,6-triamine. Alternative names: Triamterene - Impurity A and Triamterene Related Compound A.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Good laboratory practice and suitable PPE are recommended during handling.

It is used as a reference standard for trace-level detection and quantitation of nitrosamine impurities by LC-MS/MS or GC-MS, supporting nitrosamine risk assessments for Triamterene, method validation (AMV) and regulatory filings. 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.
