Chemical Structure
Description
CATO supplies tert-Butyl 4,4-difluoro-3-((methylsulfonyl)oxy)piperidine-1-carboxylate (CAS 1881288-58-9), a certified reference material (molecular formula C11H19F2NO5S, MW 315.33 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, tert-Butyl 4,4-difluoro-3-((methylsulfonyl)oxy)piperidine-1-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 315.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures tert-Butyl 4,4-difluoro-3-((methylsulfonyl)oxy)piperidine-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.
