Chemical Structure
Description
(4-Chloro-3-nitrophenyl)(pyrrolidin-1-yl)methanone (CAS 288154-78-9), molecular formula C11H11ClN2O3 and molecular weight 254.67 g/mol, is a CATO reference standard with documented purity and traceability.
(4-Chloro-3-nitrophenyl)(pyrrolidin-1-yl)methanone (C11H11ClN2O3) 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 (4-Chloro-3-nitrophenyl)(pyrrolidin-1-yl)methanone 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.
