Description
CATO manufactures 5,6,7,8-Tetrahydro-α,5,5,8,8-pentamethyl-2-naphthalenemethanol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
5,6,7,8-Tetrahydro-α,5,5,8,8-pentamethyl-2-naphthalenemethanol (CAS 69251-25-8) is a high-purity analytical reference standard with the molecular formula C16H24O and a molecular weight of 232.36 g/mol.
The molecular framework of 5,6,7,8-Tetrahydro-α,5,5,8,8-pentamethyl-2-naphthalenemethanol (C16H24O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
