Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,1-Dibromo-2-(4-methylphenyl)-1-ethene (CAS 60512-56-3), a certified reference material (molecular formula C9H8Br2, MW 275.97 g/mol) for analytical method development and quality control.
Owing to bromine substitution, an aromatic ring system, 1,1-Dibromo-2-(4-methylphenyl)-1-ethene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1,1-Dibromo-2-(4-methylphenyl)-1-ethene 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.
