Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
tert-Butyl 2-(4-chlorophenyl)-4-oxopiperidine-1-carboxylate (CAS 1822819-41-9) is a high-purity analytical reference standard with the molecular formula C16H20ClNO3 and a molecular weight of 309.79 g/mol.
The molecular framework of tert-Butyl 2-(4-chlorophenyl)-4-oxopiperidine-1-carboxylate (C16H20ClNO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
CATO manufactures tert-Butyl 2-(4-chlorophenyl)-4-oxopiperidine-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.
