Compared with other compounds in its class, the molecular weight of 313.41 g/mol gives [(1Z,3E)-2-(Benzenesulfonyl)-4-phenylbuta-1,3-dien-1-yl]dimethylamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
[(1Z,3E)-2-(Benzenesulfonyl)-4-phenylbuta-1,3-dien-1-yl]dimethylamine (CAS 343375-17-7) is a high-purity analytical reference standard with the molecular formula C18H19NO2S and a molecular weight of 313.41 g/mol.
Structurally, [(1Z,3E)-2-(Benzenesulfonyl)-4-phenylbuta-1,3-dien-1-yl]dimethylamine (C18H19NO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 313.41 g/mol, it falls into the moderately-high-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.
