(Z)-4,4,4-trifluoro-3-methylbut-2-enoic acid CAS 93404-33-2

Description

As a certified reference material (CRM), (Z)-4,4,4-trifluoro-3-methylbut-2-enoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies (Z)-4,4,4-trifluoro-3-methylbut-2-enoic acid (CAS 93404-33-2), a certified reference material (molecular formula C5H5F3O2, MW 154.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H5F3O2, (Z)-4,4,4-trifluoro-3-methylbut-2-enoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 154.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
