4-Cyclopropyl-5-(p-tolyl)-4h-1,2,4-triazole-3-thiol CAS 919970-63-1

Description

As a certified reference material (CRM), 4-Cyclopropyl-5-(p-tolyl)-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.

4-Cyclopropyl-5-(p-tolyl)-4h-1,2,4-triazole-3-thiol (CAS 919970-63-1) is a high-purity analytical reference standard with the molecular formula C12H13N3S and a molecular weight of 231.32 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Cyclopropyl-5-(p-tolyl)-4h-1,2,4-triazole-3-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 231.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
