Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1-(2,2-difluoro-1-methylcyclopropyl)ethanone.
CATO supplies 2-Bromo-1-(2,2-difluoro-1-methylcyclopropyl)ethanone (CAS 128073-31-4), a certified reference material (molecular formula C6H7BrF2O, MW 213.02 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, 2-Bromo-1-(2,2-difluoro-1-methylcyclopropyl)ethanone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.02 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), 2-Bromo-1-(2,2-difluoro-1-methylcyclopropyl)ethanone 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.
