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-bis(4-methoxyphenyl)ethan-1-one.
2-Bromo-1,2-bis(4-methoxyphenyl)ethan-1-one (CAS 27895-95-0) is a high-purity analytical reference standard with the molecular formula C16H15BrO3 and a molecular weight of 335.19 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 2-Bromo-1,2-bis(4-methoxyphenyl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-bis(4-methoxyphenyl)ethan-1-one 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.
