Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 323.81 g/mol gives Tert-butyl 4-(4-chlorobenzoyl)piperidine-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tert-butyl 4-(4-chlorobenzoyl)piperidine-1-carboxylate (CAS 209808-06-0) is a high-purity analytical reference standard with the molecular formula C17H22ClNO3 and a molecular weight of 323.81 g/mol.
The molecular framework of Tert-butyl 4-(4-chlorobenzoyl)piperidine-1-carboxylate (C17H22ClNO3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Tert-butyl 4-(4-chlorobenzoyl)piperidine-1-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
