Chemical Structure
Description
As a certified reference material (CRM), 2-((5-((9-Chloro-6H-indolo[2,3-b]quinoxalin-6-yl)methyl)-4-(4-methoxyphenyl)-4H-1,2,4-triazol-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.
CATO supplies 2-((5-((9-Chloro-6H-indolo[2,3-b]quinoxalin-6-yl)methyl)-4-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)acetic acid (CAS 116989-81-2), a certified reference material (molecular formula C26H19ClN6O3S, MW 530.99 g/mol) for analytical method development and quality control.
The molecular framework of 2-((5-((9-Chloro-6H-indolo[2,3-b]quinoxalin-6-yl)methyl)-4-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)acetic acid (C26H19ClN6O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
