Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5-Dibromo-3-methylcyclohexane-1,2-dicarboxylic acid.
CATO supplies 4,5-Dibromo-3-methylcyclohexane-1,2-dicarboxylic acid (CAS 65941-85-7), a certified reference material (molecular formula C9H12Br2O4, MW 344.00 g/mol) for analytical method development and quality control.
4,5-Dibromo-3-methylcyclohexane-1,2-dicarboxylic acid (C9H12Br2O4) 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, 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.
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.
As a certified reference material (CRM), 4,5-Dibromo-3-methylcyclohexane-1,2-dicarboxylic 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.
