N-(3-Chloro-2-methylphenyl)-2-((4-ethyl-5-(4-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 332882-53-8

Description

The molecular framework of N-(3-Chloro-2-methylphenyl)-2-((4-ethyl-5-(4-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C19H19ClN4O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

N-(3-Chloro-2-methylphenyl)-2-((4-ethyl-5-(4-hydroxyphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 332882-53-8) is a high-purity analytical reference standard with the molecular formula C19H19ClN4O2S and a molecular weight of 402.90 g/mol.
