N-Nitroso Diazepam EP Impurity D

About N-Nitroso Diazepam EP Impurity D

N-Nitroso Diazepam EP Impurity D is a nitrosamine impurity of Temazepam carrying the CAS registry number 51145-18-7. Its molecular formula is C14H11ClN2O2 and its molecular weight is 274.7 g/mol. Systematically, it is named N-(2-benzoyl-4-chlorophenyl)-N-methylnitrous amide. It is also known as N-Nitroso Methyl Aniline Derivative or N-Nitroso N-Methyl 5-Chlorobenzophenone.

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.
