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 (2E)-N-(2-Bromophenyl)-2-(hydroxyimino)acetamide.
(2E)-N-(2-Bromophenyl)-2-(hydroxyimino)acetamide (CAS 1191245-18-7) is a high-purity analytical reference standard with the molecular formula C8H7BrN2O2 and a molecular weight of 243.06 g/mol.
(2E)-N-(2-Bromophenyl)-2-(hydroxyimino)acetamide (C8H7BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (2E)-N-(2-Bromophenyl)-2-(hydroxyimino)acetamide 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.
