3-(2,3-dimethylphenyl)-4'-thiomethylpropiophenone CAS 898769-38-5

Description

The occurrence of 3-(2,3-dimethylphenyl)-4'-thiomethylpropiophenone is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(2,3-dimethylphenyl)-4'-thiomethylpropiophenone (CAS 898769-38-5), molecular formula C18H17F3O and molecular weight 306.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(2,3-dimethylphenyl)-4'-thiomethylpropiophenone (C18H17F3O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 306.32 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
