Compared with other compounds in its class, the molecular weight of 204.65 g/mol gives 5-Chloro-1,2-dihydro-1-acenaphthylenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-1,2-dihydro-1-acenaphthylenol (CAS 1055321-78-2) is a high-purity analytical reference standard with the molecular formula C12H9ClO and a molecular weight of 204.65 g/mol.
The molecular framework of 5-Chloro-1,2-dihydro-1-acenaphthylenol (C12H9ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, 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 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.
