CATO supplies (4r)-1-Tert-butoxycarbonyl-3,3-difluoro-piperidine-4-carboxylicacid (CAS 2382269-75-0), a certified reference material (molecular formula C11H17F2NO4, MW 265.25 g/mol) for analytical method development and quality control.

(4r)-1-Tert-butoxycarbonyl-3,3-difluoro-piperidine-4-carboxylicacid (C11H17F2NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), (4r)-1-Tert-butoxycarbonyl-3,3-difluoro-piperidine-4-carboxylicacid 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.
