Chemical Structure
Description
The occurrence of 816455-27-3 tert-butyl 3-(chlorocarbonyl)piperidine-1-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
816455-27-3 tert-butyl 3-(chlorocarbonyl)piperidine-1-carboxylate (CAS 816455-27-3), molecular formula C11H18ClNO3 and molecular weight 247.72 g/mol, is a CATO reference standard with documented purity and traceability.
816455-27-3 tert-butyl 3-(chlorocarbonyl)piperidine-1-carboxylate (C11H18ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 816455-27-3 tert-butyl 3-(chlorocarbonyl)piperidine-1-carboxylate 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.
