Chemical Structure

Benzo[b]naphtho[1,2-d]thiophene CAS 205-43-6 chemical structure

Description

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.

Benzo[b]naphtho[1,2-d]thiophene (CAS 205-43-6) is a high-purity analytical reference standard with the molecular formula C16H10S and a molecular weight of 234.32 g/mol.

Owing to sulfur-containing functionality, a polycyclic aromatic system, Benzo[b]naphtho[1,2-d]thiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
