Compared with other compounds in its class, the molecular weight of 122.16 g/mol gives 2,3-Dimethylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3-Dimethylphenol (CAS 526-75-0), molecular formula C8H10O and molecular weight 122.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,3-Dimethylphenol (C8H10O) contains 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 122.16 g/mol, it falls into the low-molecular-weight range. 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.
