5-[(2-Chlorophenoxy)methyl]-4-ethyl-4H-1,2,4-triazole-3-thiol CAS 403990-80-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-[(2-Chlorophenoxy)methyl]-4-ethyl-4H-1,2,4-triazole-3-thiol.

5-[(2-Chlorophenoxy)methyl]-4-ethyl-4H-1,2,4-triazole-3-thiol (CAS 403990-80-7), molecular formula C11H12ClN3OS and molecular weight 269.75 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H12ClN3OS, 5-[(2-Chlorophenoxy)methyl]-4-ethyl-4H-1,2,4-triazole-3-thiol contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 5-[(2-Chlorophenoxy)methyl]-4-ethyl-4H-1,2,4-triazole-3-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
