Chemical Structure

3-(4-Bromophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-5-ol CAS 187812-07-3 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 3-(4-Bromophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-5-ol.

3-(4-Bromophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-5-ol (CAS 187812-07-3) is a high-purity analytical reference standard with the molecular formula C10H7BrF3NO2 and a molecular weight of 310.07 g/mol.

The molecular framework of 3-(4-Bromophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-5-ol (C10H7BrF3NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
