Chemical Structure
Description
The occurrence of 2-Amino-6-methoxybenzenethiol is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Amino-6-methoxybenzenethiol (CAS 740773-51-7) is a high-purity analytical reference standard with the molecular formula C7H9NOS and a molecular weight of 155.22 g/mol.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Amino-6-methoxybenzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.22 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).
