Chemical Structure
Description
As a certified reference material (CRM), Dimethyl 2-(bromomethyl)isophthalate 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.
CATO supplies Dimethyl 2-(bromomethyl)isophthalate (CAS 16281-93-9), a certified reference material (molecular formula C11H11BrO4, MW 287.11 g/mol) for analytical method development and quality control.
Dimethyl 2-(bromomethyl)isophthalate (C11H11BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. 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.
