Chemical Structure

5-(4-Chlorophenyl)-N-ethylisoxazol-3-amine CAS 91076-73-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-Chlorophenyl)-N-ethylisoxazol-3-amine.

5-(4-Chlorophenyl)-N-ethylisoxazol-3-amine (CAS 91076-73-2) is a high-purity analytical reference standard with the molecular formula C11H11ClN2O and a molecular weight of 222.67 g/mol.

The molecular framework of 5-(4-Chlorophenyl)-N-ethylisoxazol-3-amine (C11H11ClN2O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-(4-Chlorophenyl)-N-ethylisoxazol-3-amine 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.
