Chemical Structure

2,2'-(Bromomethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) CAS 52293-05-7 chemical structure

Description

The occurrence of 2,2'-(Bromomethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2'-(Bromomethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (CAS 52293-05-7), a certified reference material (molecular formula C13H25B2BrO4, MW 346.86 g/mol) for analytical method development and quality control.

2,2'-(Bromomethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (C13H25B2BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. 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), 2,2'-(Bromomethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) 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.
