Chemical Structure
Description
The occurrence of 7-(Chloromethyl)-4,5,6-triethoxyisobenzofuran-1(3H)-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-(Chloromethyl)-4,5,6-triethoxyisobenzofuran-1(3H)-one (CAS 924860-66-2) is a high-purity analytical reference standard with the molecular formula C15H19ClO5 and a molecular weight of 314.76 g/mol.
7-(Chloromethyl)-4,5,6-triethoxyisobenzofuran-1(3H)-one (C15H19ClO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
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 7-(Chloromethyl)-4,5,6-triethoxyisobenzofuran-1(3H)-one 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.
