Description
CATO supplies Sodium 5-[(4-Amino-1-naphthyl)azo]-2-[4-[(2-hydroxy-1-naphthyl)azo]-2-sulfonatostyryl]benzenesulfonate (CAS 6459-79-6), a certified reference material (molecular formula C34H25N5O7S2Na, MW 702.71 g/mol) for analytical method development and quality control.
Sodium 5-[(4-Amino-1-naphthyl)azo]-2-[4-[(2-hydroxy-1-naphthyl)azo]-2-sulfonatostyryl]benzenesulfonate (C34H25N5O7S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
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), Sodium 5-[(4-Amino-1-naphthyl)azo]-2-[4-[(2-hydroxy-1-naphthyl)azo]-2-sulfonatostyryl]benzenesulfonate 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.
