3,4-dihydro-2H-1-benzopyran-4-carboxylic acid CAS 20426-80-6

Description

The occurrence of 3,4-dihydro-2H-1-benzopyran-4-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,4-dihydro-2H-1-benzopyran-4-carboxylic acid (CAS 20426-80-6), a certified reference material (molecular formula C10H16O3, MW 184.23 g/mol) for analytical method development and quality control.

3,4-dihydro-2H-1-benzopyran-4-carboxylic acid (C10H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 3,4-dihydro-2H-1-benzopyran-4-carboxylic acid 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.
