Chemical Structure

(3E)-4-ethoxy-1,1,1-trifluorobut-3-en-2-one CAS 59938-06-6 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.

CATO supplies (3E)-4-ethoxy-1,1,1-trifluorobut-3-en-2-one (CAS 59938-06-6), a certified reference material (molecular formula C6H7F3O2, MW 168.11 g/mol) for analytical method development and quality control.

(3E)-4-ethoxy-1,1,1-trifluorobut-3-en-2-one (C6H7F3O2) 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.

As a certified reference material (CRM), (3E)-4-ethoxy-1,1,1-trifluorobut-3-en-2-one 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.
