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 Trans-5-(2-chlorophenyl)-3-methyl-4,5-dihydroisoxazole-4-carbonitrile.
CATO supplies Trans-5-(2-chlorophenyl)-3-methyl-4,5-dihydroisoxazole-4-carbonitrile (CAS 62219-87-8), a certified reference material (molecular formula C11H9ClN2O, MW 220.65 g/mol) for analytical method development and quality control.
The molecular framework of Trans-5-(2-chlorophenyl)-3-methyl-4,5-dihydroisoxazole-4-carbonitrile (C11H9ClN2O) 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
