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 (1'R,2S)-2-[(1',2'-O-Isopropylidene)dihydroxyethyl]-6-fluorochroman-4-one (2S)-2-[(4R)-2,2-Dimethyl-1,3-dioxolan-4-yl]-6-fluoro-2,3-dihydro-4H-1-benzopyran-4-one 797054-19-4 (CAS 797054-19-4), a certified reference material (molecular formula C14H15FO4, MW 266.26 g/mol) for analytical method development and quality control.

Structurally, (1'R,2S)-2-[(1',2'-O-Isopropylidene)dihydroxyethyl]-6-fluorochroman-4-one (2S)-2-[(4R)-2,2-Dimethyl-1,3-dioxolan-4-yl]-6-fluoro-2,3-dihydro-4H-1-benzopyran-4-one 797054-19-4 (C14H15FO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 266.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), (1'R,2S)-2-[(1',2'-O-Isopropylidene)dihydroxyethyl]-6-fluorochroman-4-one (2S)-2-[(4R)-2,2-Dimethyl-1,3-dioxolan-4-yl]-6-fluoro-2,3-dihydro-4H-1-benzopyran-4-one 797054-19-4 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.
