Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 142.08 g/mol gives 3,3,3-Trifluoro-2-methylpropanoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,3,3-Trifluoro-2-methylpropanoic Acid (CAS 381-97-5), a certified reference material (molecular formula C4H5F3O2, MW 142.08 g/mol) for analytical method development and quality control.
3,3,3-Trifluoro-2-methylpropanoic Acid (C4H5F3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
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 3,3,3-Trifluoro-2-methylpropanoic 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.
