Chemical Structure
Description
The occurrence of 3-Chloro-2-(methoxymethoxy)phenylboronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-2-(methoxymethoxy)phenylboronic acid (CAS 1256355-47-1), molecular formula C8H10BClO4 and molecular weight 216.43 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-2-(methoxymethoxy)phenylboronic acid (C8H10BClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Chloro-2-(methoxymethoxy)phenylboronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
