Chemical Structure
Description
The occurrence of 7,8,9,10-tetrahydrobenzo[8]annulen-5(6H)-one is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7,8,9,10-tetrahydrobenzo[8]annulen-5(6H)-one (CAS 829-14-1) is a high-purity analytical reference standard with the molecular formula C12H14O and a molecular weight of 174.24 g/mol.
7,8,9,10-tetrahydrobenzo[8]annulen-5(6H)-one (C12H14O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
