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-Fluoro-3-methylphenyl)isoxazol-3-amine.
5-(4-Fluoro-3-methylphenyl)isoxazol-3-amine (CAS 1267110-00-8) is a high-purity analytical reference standard with the molecular formula C10H9FN2O and a molecular weight of 192.19 g/mol.
The molecular framework of 5-(4-Fluoro-3-methylphenyl)isoxazol-3-amine (C10H9FN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-(4-Fluoro-3-methylphenyl)isoxazol-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.
