The occurrence of 4-(Cyclohex-1-en-1-yl)-2-methylthiophene is closely related to sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(Cyclohex-1-en-1-yl)-2-methylthiophene (CAS 40196-63-2), a certified reference material (molecular formula C11H14S, MW 178.29 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, an aromatic ring system, 4-(Cyclohex-1-en-1-yl)-2-methylthiophene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 178.29 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.
