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 Diethyl2-bromo-2-fluoro-malonate.
CATO supplies Diethyl2-bromo-2-fluoro-malonate (CAS 756-44-5), a certified reference material (molecular formula C7H10BrFO4, MW 257.05 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, Diethyl2-bromo-2-fluoro-malonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.05 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.
CATO manufactures Diethyl2-bromo-2-fluoro-malonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
