(3-Methoxy-1,2-phenylene)dimethanol (CAS 90047-52-2), molecular formula C9H12O3 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3-Methoxy-1,2-phenylene)dimethanol (C9H12O3) 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 168.19 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.
