Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-bromo-1,5-bis(chloromethyl)-2,4-dimethylbenzene.
3-bromo-1,5-bis(chloromethyl)-2,4-dimethylbenzene (CAS 79539-15-4) is a high-purity analytical reference standard with the molecular formula C10H11BrCl2 and a molecular weight of 282.00 g/mol.
3-bromo-1,5-bis(chloromethyl)-2,4-dimethylbenzene (C10H11BrCl2) contains chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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-bromo-1,5-bis(chloromethyl)-2,4-dimethylbenzene 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.
