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.
5,5,5-Trifluoro-4,4-dihydroxypentanoic acid (CAS 45021-39-4), molecular formula C5H7F3O4 and molecular weight 188.10 g/mol, is a CATO reference standard with documented purity and traceability.
5,5,5-Trifluoro-4,4-dihydroxypentanoic acid (C5H7F3O4) contains a carbohydrate-derived structure, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 5,5,5-Trifluoro-4,4-dihydroxypentanoic 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.
