N-allyl-3-(2-chloro-6-fluorophenyl)-5-methylisoxazole-4-carboxamide CAS 536725-77-6 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 N-allyl-3-(2-chloro-6-fluorophenyl)-5-methylisoxazole-4-carboxamide.

N-allyl-3-(2-chloro-6-fluorophenyl)-5-methylisoxazole-4-carboxamide (CAS 536725-77-6) is a high-purity analytical reference standard with the molecular formula C14H12ClFN2O2 and a molecular weight of 294.71 g/mol.

N-allyl-3-(2-chloro-6-fluorophenyl)-5-methylisoxazole-4-carboxamide (C14H12ClFN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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.
