CATO supplies O7CFS23KOR 541-70-8 1,3-Benzenediamine sulfate m-Phenylenediamine sulfate 1,3-Phenylenediamine sulfate 1,3-Benzenediamine, sulfate (1:1) Benzene-1,3-diammonium sulphate EINECS 208-791-6 HSDB 6245 m-Phenylenediamine, sulfate (1:1) UNII-O7CFS23KOR (CAS 541-70-8), a certified reference material (molecular formula C6H8N2H2O4S, MW 206.22 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, O7CFS23KOR 541-70-8 1,3-Benzenediamine sulfate m-Phenylenediamine sulfate 1,3-Phenylenediamine sulfate 1,3-Benzenediamine, sulfate (1:1) Benzene-1,3-diammonium sulphate EINECS 208-791-6 HSDB 6245 m-Phenylenediamine, sulfate (1:1) UNII-O7CFS23KOR is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.22 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.
As a certified reference material (CRM), O7CFS23KOR 541-70-8 1,3-Benzenediamine sulfate m-Phenylenediamine sulfate 1,3-Phenylenediamine sulfate 1,3-Benzenediamine, sulfate (1:1) Benzene-1,3-diammonium sulphate EINECS 208-791-6 HSDB 6245 m-Phenylenediamine, sulfate (1:1) UNII-O7CFS23KOR 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.
