Chemical Structure
Description
The occurrence of O,O′′-Bis[2-(methylthio)ethyl]-tert-butylcalix[4]arene is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies O,O′′-Bis[2-(methylthio)ethyl]-tert-butylcalix[4]arene (CAS 145237-25-8), a certified reference material (molecular formula C50H68O4S2, MW 797.20 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, O,O′′-Bis[2-(methylthio)ethyl]-tert-butylcalix[4]arene is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 797.20 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
