Chemical Structure
Description
The occurrence of 5,8-Dichloro-1,2,3,4-tetrahydronaphthalen-1-one is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,8-Dichloro-1,2,3,4-tetrahydronaphthalen-1-one (CAS 112933-45-6), molecular formula C10H8Cl2O and molecular weight 215.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 5,8-Dichloro-1,2,3,4-tetrahydronaphthalen-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.08 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.
