Description
As a certified reference material (CRM), 2-((5-Benzyl-5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetic acid 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.
2-((5-Benzyl-5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetic acid (CAS 443121-77-5), molecular formula C18H14N4O2S and molecular weight 350.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((5-Benzyl-5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
