Chemical Structure
Description
tert-Butyl (S)-3,3-difluoro-4-(methylamino)piperidine-1-carboxylate (CAS 2820191-00-0), molecular formula C11H20F2N2O2 and molecular weight 250.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl (S)-3,3-difluoro-4-(methylamino)piperidine-1-carboxylate (C11H20F2N2O2) 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.
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 (S)-3,3-difluoro-4-(methylamino)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.
