Chemical Structure
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.
2-(2-Methylcyclohex-1-en-1-yl)benzo[b]thiophene (CAS 55084-50-9), molecular formula C15H16S and molecular weight 228.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a polycyclic aromatic system, 2-(2-Methylcyclohex-1-en-1-yl)benzo[b]thiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 228.35 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).
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.
