Chemical Structure
Description
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.
CATO supplies 2',3'-Dihydro-4'H-spiro[cyclopentane-1,1'-naphthalen]-4'-one (CAS 4889-95-6), a certified reference material (molecular formula C14H16O, MW 200.28 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2',3'-Dihydro-4'H-spiro[cyclopentane-1,1'-naphthalen]-4'-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 200.28 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.
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.
