Description
CATO manufactures (S)-4,4-Difluoropyrrolidine-2-carbaldehyde 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.
(S)-4,4-Difluoropyrrolidine-2-carbaldehyde (CAS 1357281-62-9) is a high-purity analytical reference standard with the molecular formula C5H7F2NO and a molecular weight of 135.11 g/mol.
The molecular framework of (S)-4,4-Difluoropyrrolidine-2-carbaldehyde (C5H7F2NO) is characterized by an amide 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
