Chemical Structure

6-Chloro-2H-1,3-benzodioxole-5-carboxylic acid CAS 2591-26-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 200.58 g/mol gives 6-Chloro-2H-1,3-benzodioxole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Chloro-2H-1,3-benzodioxole-5-carboxylic acid (CAS 2591-26-6) is a high-purity analytical reference standard with the molecular formula C8H5ClO4 and a molecular weight of 200.58 g/mol.

6-Chloro-2H-1,3-benzodioxole-5-carboxylic acid (C8H5ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. 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 6-Chloro-2H-1,3-benzodioxole-5-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.
