Chemical Structure
Description
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 supplies Ethyl 4-((2-chlorobenzoyl)oxy)-3-methylbenzofuran-2-carboxylate (CAS 356586-77-1), a certified reference material (molecular formula C19H15ClO5, MW 358.77 g/mol) for analytical method development and quality control.
Ethyl 4-((2-chlorobenzoyl)oxy)-3-methylbenzofuran-2-carboxylate (C19H15ClO5) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
CATO manufactures Ethyl 4-((2-chlorobenzoyl)oxy)-3-methylbenzofuran-2-carboxylate 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.
