Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1,4,4,7-Pentamethyl-1,2,3,4-tetrahydronaphthalen-2-ol (CAS 167958-78-3), molecular formula C15H22O and molecular weight 218.33 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,1,4,4,7-Pentamethyl-1,2,3,4-tetrahydronaphthalen-2-ol (C15H22O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 218.33 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).
