Compared with other compounds in its class, the molecular weight of 210.27 g/mol gives Methyl 3-hydroxyadamantane-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 3-hydroxyadamantane-1-carboxylate (CAS 68435-07-4), molecular formula C12H18O3 and molecular weight 210.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 3-hydroxyadamantane-1-carboxylate (C12H18O3) 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 210.27 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.
