Chemical Structure
Description
1,2-Dihydroxy-3,4-epoxy-1,2,3,4-tetrahydrophenanthrene (CAS 67737-62-6) is a high-purity analytical reference standard with the molecular formula C14H22O3 and a molecular weight of 238.32 g/mol.
Structurally, 1,2-Dihydroxy-3,4-epoxy-1,2,3,4-tetrahydrophenanthrene (C14H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 238.32 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.
