Chemical Structure

7-Chloro-1-methoxydibenzo[b,d]furan-4-carboxylic acid CAS 1956379-97-7 chemical structure

Description

The occurrence of 7-Chloro-1-methoxydibenzo[b,d]furan-4-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Chloro-1-methoxydibenzo[b,d]furan-4-carboxylic acid (CAS 1956379-97-7), molecular formula C14H9ClO4 and molecular weight 276.67 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 7-Chloro-1-methoxydibenzo[b,d]furan-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Chloro-1-methoxydibenzo[b,d]furan-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.
