Chemical Structure
Description
2-Fluoro-5,8-dioxaspiro[3.4]Octane-2-carboxylic acid (CAS 2227204-92-2), molecular formula C7H9FO4 and molecular weight 176.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Fluoro-5,8-dioxaspiro[3.4]Octane-2-carboxylic acid (C7H9FO4) 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 2-Fluoro-5,8-dioxaspiro[3.4]Octane-2-carboxylic acid 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.
