Description

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.

(E)-3-(5-Chlorothiophen-2-yl)-2-(4-phenylpiperazine-1-carbonyl)acrylonitrile (CAS 1164466-58-3) is a high-purity analytical reference standard with the molecular formula C18H16ClN3OS and a molecular weight of 357.86 g/mol.

Based on its molecular formula C18H16ClN3OS, (E)-3-(5-Chlorothiophen-2-yl)-2-(4-phenylpiperazine-1-carbonyl)acrylonitrile contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 357.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
