Chemical Structure

3-(5-Ethyl-4H-1,2,4-triazol-3-yl)aniline CAS 915921-65-2 chemical structure

Description

3-(5-Ethyl-4H-1,2,4-triazol-3-yl)aniline (CAS 915921-65-2), molecular formula C10H12N4 and molecular weight 188.23 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H12N4, 3-(5-Ethyl-4H-1,2,4-triazol-3-yl)aniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.23 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.

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), 3-(5-Ethyl-4H-1,2,4-triazol-3-yl)aniline 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.
