Chemical Structure

6,8-Dichloro-2-oxo-2H-chromene-3-carboxamide CAS 101166-95-4 chemical structure

Description

CATO manufactures 6,8-Dichloro-2-oxo-2H-chromene-3-carboxamide 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.

CATO supplies 6,8-Dichloro-2-oxo-2H-chromene-3-carboxamide (CAS 101166-95-4), a certified reference material (molecular formula C10H5Cl2NO3, MW 258.06 g/mol) for analytical method development and quality control.

6,8-Dichloro-2-oxo-2H-chromene-3-carboxamide (C10H5Cl2NO3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
