4-Cyclopentyl-5-ethyl-4h-1,2,4-triazole-3-thiol CAS 1038330-15-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Cyclopentyl-5-ethyl-4h-1,2,4-triazole-3-thiol.

4-Cyclopentyl-5-ethyl-4h-1,2,4-triazole-3-thiol (CAS 1038330-15-2), molecular formula C9H15N3S and molecular weight 197.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Cyclopentyl-5-ethyl-4h-1,2,4-triazole-3-thiol (C9H15N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-Cyclopentyl-5-ethyl-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.
