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 1-(5-Chloro-2-hydroxy-4-methyl-3-nitrophenyl)ethan-1-one.
1-(5-Chloro-2-hydroxy-4-methyl-3-nitrophenyl)ethan-1-one (CAS 288401-07-0) is a high-purity analytical reference standard with the molecular formula C9H8ClNO4 and a molecular weight of 229.62 g/mol.
1-(5-Chloro-2-hydroxy-4-methyl-3-nitrophenyl)ethan-1-one (C9H8ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-(5-Chloro-2-hydroxy-4-methyl-3-nitrophenyl)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.
