Chemical Structure
Description
9,9-difluoro-1,4-dioxaspiro[5.5]undecan-5-one (CAS 2044712-58-3), molecular formula C9H12F2O3 and molecular weight 206.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9,9-difluoro-1,4-dioxaspiro[5.5]undecan-5-one (C9H12F2O3) is characterized by a carboxylic acid group, 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.
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 9,9-difluoro-1,4-dioxaspiro[5.5]undecan-5-one 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.
