Chemical Structure
Description
The occurrence of 2-Methyl-2,3-dihydro-1h-cyclopenta[a]naphthalen-1-ol is closely related to a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methyl-2,3-dihydro-1h-cyclopenta[a]naphthalen-1-ol (CAS 163801-85-2), molecular formula C14H14O and molecular weight 198.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-Methyl-2,3-dihydro-1h-cyclopenta[a]naphthalen-1-ol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Methyl-2,3-dihydro-1h-cyclopenta[a]naphthalen-1-ol 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.
