4-Chloro-2-(3-ethyl-1,2,4-oxadiazol-5-yl)aniline CAS 1040345-45-6

Description

4-Chloro-2-(3-ethyl-1,2,4-oxadiazol-5-yl)aniline (CAS 1040345-45-6), molecular formula C10H10ClN3O and molecular weight 223.66 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloro-2-(3-ethyl-1,2,4-oxadiazol-5-yl)aniline (C10H10ClN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 4-Chloro-2-(3-ethyl-1,2,4-oxadiazol-5-yl)aniline 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.
