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-chloro-4-pyridyl)ethanone.
CATO supplies 2-Bromo-1-(2-chloro-4-pyridyl)ethanone (CAS 23794-16-3), a certified reference material (molecular formula C7H5BrClNO, MW 234.48 g/mol) for analytical method development and quality control.
2-Bromo-1-(2-chloro-4-pyridyl)ethanone (C7H5BrClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-Bromo-1-(2-chloro-4-pyridyl)ethanone 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.
