Chemical Structure
Description
The occurrence of 4-Amino-2-mercapto-phenol hydrochloride is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Amino-2-mercapto-phenol hydrochloride (CAS 98140-58-0) is a high-purity analytical reference standard with the molecular formula C6H7NOSHCl and a molecular weight of 177.65 g/mol.
Structurally, 4-Amino-2-mercapto-phenol hydrochloride (C6H7NOSHCl) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 177.65 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).
