Chemical Structure
Description
As a certified reference material (CRM), N,N-Bis(2-Hydroxyethyl)-P-Phenylenediamine Sulphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
N,N-Bis(2-Hydroxyethyl)-P-Phenylenediamine Sulphate (CAS 54381-16-7), molecular formula C10H16N2O2H2O4S and molecular weight 294.32 g/mol, is a CATO reference standard with documented purity and traceability.
N,N-Bis(2-Hydroxyethyl)-P-Phenylenediamine Sulphate (C10H16N2O2H2O4S) 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.
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.
