(1R,9aS)-1,9a-Dihydro-1,9a-dihydroxy-9H-fluoren-9-one CAS 149231-15-2 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 (1R,9aS)-1,9a-Dihydro-1,9a-dihydroxy-9H-fluoren-9-one.

(1R,9aS)-1,9a-Dihydro-1,9a-dihydroxy-9H-fluoren-9-one (CAS 149231-15-2) is a high-purity analytical reference standard with the molecular formula C13H10O3 and a molecular weight of 214.22 g/mol.

Based on its molecular formula C13H10O3, (1R,9aS)-1,9a-Dihydro-1,9a-dihydroxy-9H-fluoren-9-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
