(4R,5R)-5-(2,4-Difluorophenyl)-4-methyl-5-(1H-1,2,4-triazol-1-ylmethyl)-2-oxazolidinone-d3 CAS 1330176-89-0 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 (4R,5R)-5-(2,4-Difluorophenyl)-4-methyl-5-(1H-1,2,4-triazol-1-ylmethyl)-2-oxazolidinone-d3.

(4R,5R)-5-(2,4-Difluorophenyl)-4-methyl-5-(1H-1,2,4-triazol-1-ylmethyl)-2-oxazolidinone-d3 (CAS 1330176-89-0) is a high-purity analytical reference standard with the molecular formula C13H9D3F2N4O2 and a molecular weight of 297.28 g/mol.

(4R,5R)-5-(2,4-Difluorophenyl)-4-methyl-5-(1H-1,2,4-triazol-1-ylmethyl)-2-oxazolidinone-d3 (C13H9D3F2N4O2) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 (4R,5R)-5-(2,4-Difluorophenyl)-4-methyl-5-(1H-1,2,4-triazol-1-ylmethyl)-2-oxazolidinone-d3 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.
