Chemical Structure

5-Methyl-3-phenylisoxazol-4-amine CAS 21169-65-3 chemical structure

Description

The molecular framework of 5-Methyl-3-phenylisoxazol-4-amine (C10H10N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

5-Methyl-3-phenylisoxazol-4-amine (CAS 21169-65-3) is a high-purity analytical reference standard with the molecular formula C10H10N2O and a molecular weight of 174.20 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 5-Methyl-3-phenylisoxazol-4-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.
