Chemical Structure
Description
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.
CATO supplies (2E)-3-(2-Chloro-6-fluorophenyl)-1-(2,4-dimethylphenyl)prop-2-en-1-one (CAS 1354942-37-2), a certified reference material (molecular formula C17H14ClFO, MW 288.74 g/mol) for analytical method development and quality control.
Structurally, (2E)-3-(2-Chloro-6-fluorophenyl)-1-(2,4-dimethylphenyl)prop-2-en-1-one (C17H14ClFO) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine 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 288.74 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.
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.
