4-amino-5-(3-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol CAS 893727-09-8

Description

The occurrence of 4-amino-5-(3-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-amino-5-(3-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol (CAS 893727-09-8), molecular formula C10H12N4OS and molecular weight 236.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-amino-5-(3-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
