Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-5-chloro-3,4-difluoro-2-iodobenzene.
CATO supplies 1-Bromo-5-chloro-3,4-difluoro-2-iodobenzene (CAS 2451256-38-3), a certified reference material (molecular formula C6HBrClF2I, MW 353.33 g/mol) for analytical method development and quality control.
Owing to fluorine/chlorine/bromine/iodine substitution, an aromatic ring system, 1-Bromo-5-chloro-3,4-difluoro-2-iodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.33 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.
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), 1-Bromo-5-chloro-3,4-difluoro-2-iodobenzene 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.
