Ethyl 3-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methoxy)pyrido[1,2-a]indole-10-carboxylate CAS 339106-92-2

Description

As a certified reference material (CRM), Ethyl 3-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methoxy)pyrido[1,2-a]indole-10-carboxylate 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.

Ethyl 3-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methoxy)pyrido[1,2-a]indole-10-carboxylate (CAS 339106-92-2) is a high-purity analytical reference standard with the molecular formula C20H20N4O3S and a molecular weight of 396.46 g/mol.

The molecular framework of Ethyl 3-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methoxy)pyrido[1,2-a]indole-10-carboxylate (C20H20N4O3S) is characterized by a steroid core, 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
