Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1,2-Dihydroacenaphthylen-3-yl)ethan-1-one.
1-(1,2-Dihydroacenaphthylen-3-yl)ethan-1-one (CAS 7434-96-0) is a high-purity analytical reference standard with the molecular formula C14H12O and a molecular weight of 196.24 g/mol.
Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1-(1,2-Dihydroacenaphthylen-3-yl)ethan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.24 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
