Chemical Structure

N,N-Diethylsulfamic Acid CAS 42731-89-5 chemical structure

Description

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.

N,N-Diethylsulfamic Acid (CAS 42731-89-5), molecular formula C4H11NO3S and molecular weight 153.20 g/mol, is a CATO reference standard with documented purity and traceability.

N,N-Diethylsulfamic Acid (C4H11NO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures N,N-Diethylsulfamic Acid 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.
