Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Ethyl (4S,5R)-4-hydroxy-5-methyl-5-(trifluoromethyl)-4,5-dihydrofuran-2-carboxylate (CAS 2878423-91-5) is a high-purity analytical reference standard with the molecular formula C9H11F3O4 and a molecular weight of 240.18 g/mol.
The molecular framework of Ethyl (4S,5R)-4-hydroxy-5-methyl-5-(trifluoromethyl)-4,5-dihydrofuran-2-carboxylate (C9H11F3O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
