N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-((4-ethyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 557063-71-5

Description

N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-((4-ethyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 557063-71-5) is a high-purity analytical reference standard with the molecular formula C19H19N5O3S and a molecular weight of 397.45 g/mol.

The molecular framework of N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-((4-ethyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C19H19N5O3S) 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).

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