(3-Phenyl-1,2-oxazol-5-yl)methanesulfonyl chloride CAS 1087792-39-9

Description

Compared with other compounds in its class, the molecular weight of 257.69 g/mol gives (3-Phenyl-1,2-oxazol-5-yl)methanesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-Phenyl-1,2-oxazol-5-yl)methanesulfonyl chloride (CAS 1087792-39-9), molecular formula C10H8ClNO3S and molecular weight 257.69 g/mol, is a CATO reference standard with documented purity and traceability.

(3-Phenyl-1,2-oxazol-5-yl)methanesulfonyl chloride (C10H8ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
