Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ammonium 2-aminoethane-1,1-disulfonic acid hydrate, min. 95%.
CATO supplies Ammonium 2-aminoethane-1,1-disulfonic acid hydrate, min. 95% (CAS 1235825-84-9), a certified reference material (molecular formula C2H7NO6S2H2OH3N, MW 240.25 g/mol) for analytical method development and quality control.
Ammonium 2-aminoethane-1,1-disulfonic acid hydrate, min. 95% (C2H7NO6S2H2OH3N) contains an amide group, a sulfone group, a carboxylic acid 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.
As a certified reference material (CRM), Ammonium 2-aminoethane-1,1-disulfonic acid hydrate, min. 95% 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.
