Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,7-Dibromo-10-(2-ethylhexyl)-10H-phenothiazine (CAS 264263-98-1), molecular formula C20H23Br2NS and molecular weight 469.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 3,7-Dibromo-10-(2-ethylhexyl)-10H-phenothiazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 469.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3,7-Dibromo-10-(2-ethylhexyl)-10H-phenothiazine 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.
