4,4,4-Trifluorobut-2-ynoic acid CAS 120801-99-2

Description

Compared with other compounds in its class, the molecular weight of 138.04 g/mol gives 4,4,4-Trifluorobut-2-ynoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4,4,4-Trifluorobut-2-ynoic acid (CAS 120801-99-2), a certified reference material (molecular formula C4HF3O2, MW 138.04 g/mol) for analytical method development and quality control.

4,4,4-Trifluorobut-2-ynoic acid (C4HF3O2) 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 4,4,4-Trifluorobut-2-ynoic 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.
