Chemical Structure

N-Methyl-d3-N-nitroso-p-toluenesulfonamide CAS 42366-72-3 chemical structure

Description

CATO manufactures N-Methyl-d3-N-nitroso-p-toluenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

N-Methyl-d3-N-nitroso-p-toluenesulfonamide (CAS 42366-72-3), molecular formula C8H7D3N2O3S and molecular weight 217.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-Methyl-d3-N-nitroso-p-toluenesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
