Chemical Structure

(3-Mercapto-5H-[1,2,4]triazino[5,6-b]indol-5-yl)acetic acid CAS 309283-89-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (3-Mercapto-5H-[1,2,4]triazino[5,6-b]indol-5-yl)acetic acid (CAS 309283-89-4), a certified reference material (molecular formula C11H8N4O2S, MW 260.27 g/mol) for analytical method development and quality control.

The molecular framework of (3-Mercapto-5H-[1,2,4]triazino[5,6-b]indol-5-yl)acetic acid (C11H8N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
