Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Bis(bromomethyl)-2,5-diiodobenzene.
CATO supplies 1,4-Bis(bromomethyl)-2,5-diiodobenzene (CAS 56403-29-3), a certified reference material (molecular formula C8H6Br2I2, MW 515.75 g/mol) for analytical method development and quality control.
Owing to bromine/iodine substitution, an aromatic ring system, 1,4-Bis(bromomethyl)-2,5-diiodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 515.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1,4-Bis(bromomethyl)-2,5-diiodobenzene 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.
