2-(3-Chlorostyryl)-5-methyloxazole-4-carboxylic acid CAS 89724-04-9

Description

The occurrence of 2-(3-Chlorostyryl)-5-methyloxazole-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3-Chlorostyryl)-5-methyloxazole-4-carboxylic acid (CAS 89724-04-9), molecular formula C13H10ClNO3 and molecular weight 263.68 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3-Chlorostyryl)-5-methyloxazole-4-carboxylic acid (C13H10ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
