4-((1-(Naphthalen-2-ylsulfonyl)-1H-benzo[d]imidazol-2-yl)thio)but-2-yn-1-ol CAS 727386-35-8

Description

The occurrence of 4-((1-(Naphthalen-2-ylsulfonyl)-1H-benzo[d]imidazol-2-yl)thio)but-2-yn-1-ol is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-((1-(Naphthalen-2-ylsulfonyl)-1H-benzo[d]imidazol-2-yl)thio)but-2-yn-1-ol (CAS 727386-35-8) is a high-purity analytical reference standard with the molecular formula C21H16N2O3S2 and a molecular weight of 408.49 g/mol.

Based on its molecular formula C21H16N2O3S2, 4-((1-(Naphthalen-2-ylsulfonyl)-1H-benzo[d]imidazol-2-yl)thio)but-2-yn-1-ol contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 408.49 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).

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.
