Chemical Structure

7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-ol CAS 1216251-64-7 chemical structure

Description

The occurrence of 7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-ol 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.

CATO supplies 7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-ol (CAS 1216251-64-7), a certified reference material (molecular formula C8H7ClO3, MW 186.59 g/mol) for analytical method development and quality control.

7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-ol (C8H7ClO3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-ol 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.
