N,N-diethyl-1-(1-methyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine-3-carbonyl)piperidine-3-carboxamide hydrochloride (CAS 1257856-45-3), molecular formula C18H29N5O2HCl and molecular weight 383.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N,N-diethyl-1-(1-methyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine-3-carbonyl)piperidine-3-carboxamide hydrochloride (C18H29N5O2HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures N,N-diethyl-1-(1-methyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine-3-carbonyl)piperidine-3-carboxamide hydrochloride 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.
