Chemical Structure

9-Hydroxybenz[a]anthracene CAS 34570-62-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 244.29 g/mol gives 9-Hydroxybenz[a]anthracene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

9-Hydroxybenz[a]anthracene (CAS 34570-62-2) is a high-purity analytical reference standard with the molecular formula C18H12O and a molecular weight of 244.29 g/mol.

Structurally, 9-Hydroxybenz[a]anthracene (C18H12O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 244.29 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
