1-(4-Ethoxyphenyl)-2-((2-fluorophenyl)sulfonyl)ethan-1-one CAS 1326863-45-9

Description

The occurrence of 1-(4-Ethoxyphenyl)-2-((2-fluorophenyl)sulfonyl)ethan-1-one is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Ethoxyphenyl)-2-((2-fluorophenyl)sulfonyl)ethan-1-one (CAS 1326863-45-9), molecular formula C16H15FO4S and molecular weight 322.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(4-Ethoxyphenyl)-2-((2-fluorophenyl)sulfonyl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.35 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.

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.

As a certified reference material (CRM), 1-(4-Ethoxyphenyl)-2-((2-fluorophenyl)sulfonyl)ethan-1-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.
