Chemical Structure
Description
CATO supplies 2,2'-((2-((Carboxymethyl)thio)ethyl)azanediyl)diacetic acid hydrate (CAS 81877-53-4), a certified reference material (molecular formula C8H13NO6SH2O, MW 269.27 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 2,2'-((2-((Carboxymethyl)thio)ethyl)azanediyl)diacetic acid hydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2'-((2-((Carboxymethyl)thio)ethyl)azanediyl)diacetic acid hydrate 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.
