About Nitroso Irbesartan

Nitroso Irbesartan (CAS 2768787-11-5) is a nitrosamine impurity of Irbesartan offered by Vaqora Chemicals. Its molecular formula is C25H27N7O2 and its molecular weight is 457.5 g/mol. Systematically, it is named 2-butyl-3-[[4-[2-(2-nitrosotetrazol-5-yl)phenyl]phenyl]methyl]-1,3-diazaspiro[4.4]non-1-en-4-one. Common synonyms include N-Nitroso Irbesartan.

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.

Laboratories use this nitrosamine standard to develop and validate highly sensitive LC-MS/MS methods, to confirm limits of detection and to document nitrosamine risk assessments in regulatory submissions. 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.
