Chemical Structure
Description
trans-1-Boc-4-(4-chlorophenyl)-pyrrolidine-3-carboxylic acid (CAS 851485-00-2), molecular formula C16H20ClNO4 and molecular weight 325.79 g/mol, is a CATO reference standard with documented purity and traceability.
trans-1-Boc-4-(4-chlorophenyl)-pyrrolidine-3-carboxylic acid (C16H20ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 trans-1-Boc-4-(4-chlorophenyl)-pyrrolidine-3-carboxylic acid 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.
