Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(Benzo[b]thiophen-2-yl)-1H-indole.
5-(Benzo[b]thiophen-2-yl)-1H-indole (CAS 885273-14-3) is a high-purity analytical reference standard with the molecular formula C16H11NS and a molecular weight of 249.33 g/mol.
Based on its molecular formula C16H11NS, 5-(Benzo[b]thiophen-2-yl)-1H-indole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
