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 4,4-difluoro-3-(2-oxopropyl)piperidine-1-carboxylate (CAS 2101206-55-5), molecular formula C13H21F2NO3 and molecular weight 277.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 4,4-difluoro-3-(2-oxopropyl)piperidine-1-carboxylate (C13H21F2NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
As a certified reference material (CRM), tert-Butyl 4,4-difluoro-3-(2-oxopropyl)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.
