Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
4,4-Difluoropentanal (CAS 1546331-97-8), molecular formula C5H8F2O and molecular weight 122.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4-Difluoropentanal (C5H8F2O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
