Chemical Structure
Description
1-(5-(Dimethylamino)-4-phenylthiophen-2-yl)ethan-1-one (CAS 343375-57-5), molecular formula C14H15NOS and molecular weight 245.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(5-(Dimethylamino)-4-phenylthiophen-2-yl)ethan-1-one (C14H15NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 245.34 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
