(5-Phenylisoxazol-3-yl)methyl 3,4-dichlorobenzoate CAS 343374-57-2

Description

As a certified reference material (CRM), (5-Phenylisoxazol-3-yl)methyl 3,4-dichlorobenzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(5-Phenylisoxazol-3-yl)methyl 3,4-dichlorobenzoate (CAS 343374-57-2), molecular formula C17H11Cl2NO3 and molecular weight 348.18 g/mol, is a CATO reference standard with documented purity and traceability.

(5-Phenylisoxazol-3-yl)methyl 3,4-dichlorobenzoate (C17H11Cl2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
