Chemical Structure

(S)-Benzyl (1-fluoro-2-(2-fluorophenyl)-4-oxobutan-2-yl)carbamate CAS 2091721-25-2 chemical structure

Description

The occurrence of (S)-Benzyl (1-fluoro-2-(2-fluorophenyl)-4-oxobutan-2-yl)carbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-Benzyl (1-fluoro-2-(2-fluorophenyl)-4-oxobutan-2-yl)carbamate (CAS 2091721-25-2), a certified reference material (molecular formula C18H17F2NO3, MW 333.33 g/mol) for analytical method development and quality control.

Structurally, (S)-Benzyl (1-fluoro-2-(2-fluorophenyl)-4-oxobutan-2-yl)carbamate (C18H17F2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 333.33 g/mol, it falls into the moderately-high-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.

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), (S)-Benzyl (1-fluoro-2-(2-fluorophenyl)-4-oxobutan-2-yl)carbamate 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.
