5-((4-Chlorophenyl)amino)-3-methylbenzo[c]isoxazole-4,7-dione CAS 51485-59-7

Description

5-((4-Chlorophenyl)amino)-3-methylbenzo[c]isoxazole-4,7-dione (CAS 51485-59-7), molecular formula C14H9ClN2O3 and molecular weight 288.69 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-((4-Chlorophenyl)amino)-3-methylbenzo[c]isoxazole-4,7-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 5-((4-Chlorophenyl)amino)-3-methylbenzo[c]isoxazole-4,7-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
