3-(3-Ethoxyphenyl)-5-(o-tolyl)-1H-1,2,4-triazole CAS 3150-82-1

Description

The occurrence of 3-(3-Ethoxyphenyl)-5-(o-tolyl)-1H-1,2,4-triazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(3-Ethoxyphenyl)-5-(o-tolyl)-1H-1,2,4-triazole (CAS 3150-82-1), a certified reference material (molecular formula C18H13ClN4O2, MW 352.77 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(3-Ethoxyphenyl)-5-(o-tolyl)-1H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.77 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.

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.

As a certified reference material (CRM), 3-(3-Ethoxyphenyl)-5-(o-tolyl)-1H-1,2,4-triazole 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.
