Description

Compared with other compounds in its class, the molecular weight of 135.55 g/mol gives 5-isoxazolecarbonyl chloride 62348-13-4 Isoxazole-5-carbonyl chloride isoxazol-5-carbonylchloride isoxazole-5-carbonylchloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-isoxazolecarbonyl chloride 62348-13-4 Isoxazole-5-carbonyl chloride isoxazol-5-carbonylchloride isoxazole-5-carbonylchloride (CAS 62348-13-4), a certified reference material (molecular formula C4H6ClNO2, MW 135.55 g/mol) for analytical method development and quality control.

5-isoxazolecarbonyl chloride 62348-13-4 Isoxazole-5-carbonyl chloride isoxazol-5-carbonylchloride isoxazole-5-carbonylchloride (C4H6ClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.
