4-Amino-5-(2-chlorophenyl)-4H-1,2,4-triazole-3-thiol CAS 13229-02-2

Description

The occurrence of 4-Amino-5-(2-chlorophenyl)-4H-1,2,4-triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Amino-5-(2-chlorophenyl)-4H-1,2,4-triazole-3-thiol (CAS 13229-02-2), a certified reference material (molecular formula C8H7ClN4S, MW 226.69 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-Amino-5-(2-chlorophenyl)-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 226.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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

As a certified reference material (CRM), 4-Amino-5-(2-chlorophenyl)-4H-1,2,4-triazole-3-thiol 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.
