Chemical Structure
Description
As a certified reference material (CRM), 2-Acetyl-3-Hydroxy-4,4,4-Trifluoro-3-(Trifluoromethyl)Butyric Acid Ethyl Ester 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.
2-Acetyl-3-Hydroxy-4,4,4-Trifluoro-3-(Trifluoromethyl)Butyric Acid Ethyl Ester (CAS 680-09-1), molecular formula C9H10F6O4 and molecular weight 296.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Acetyl-3-Hydroxy-4,4,4-Trifluoro-3-(Trifluoromethyl)Butyric Acid Ethyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
