Tert-butyl (R)-4,4-difluoro-2-(3-((4,4,4-trifluorobutyl)sulfonyl)propyl)pyrrolidine-1-carboxylate CAS 1670273-19-4 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 (R)-4,4-difluoro-2-(3-((4,4,4-trifluorobutyl)sulfonyl)propyl)pyrrolidine-1-carboxylate (CAS 1670273-19-4) is a high-purity analytical reference standard with the molecular formula C16H26F5NO4S and a molecular weight of 423.44 g/mol.

The molecular framework of Tert-butyl (R)-4,4-difluoro-2-(3-((4,4,4-trifluorobutyl)sulfonyl)propyl)pyrrolidine-1-carboxylate (C16H26F5NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 (R)-4,4-difluoro-2-(3-((4,4,4-trifluorobutyl)sulfonyl)propyl)pyrrolidine-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.
