Chemical Structure
Description
The occurrence of 3,5-Di-tert-butyl-4-hydroxybenzenesulfonic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-Di-tert-butyl-4-hydroxybenzenesulfonic acid (CAS 25679-39-4) is a high-purity analytical reference standard with the molecular formula C14H22O4S and a molecular weight of 286.39 g/mol.
Structurally, 3,5-Di-tert-butyl-4-hydroxybenzenesulfonic acid (C14H22O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 286.39 g/mol, it falls into the medium-molecular-weight range. 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).
