5-{[(4-Fluorophenyl)sulfanyl]methylene}-2,2-dimethyl-1,3-dioxane-4,6-dione CAS 477866-38-9

Description

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 5-{[(4-Fluorophenyl)sulfanyl]methylene}-2,2-dimethyl-1,3-dioxane-4,6-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

5-{[(4-Fluorophenyl)sulfanyl]methylene}-2,2-dimethyl-1,3-dioxane-4,6-dione (CAS 477866-38-9), molecular formula C13H11FO4S and molecular weight 282.29 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
