Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 162.23 g/mol gives 1-Methyl-5,6,7,8-tetrahydronaphthalen-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Methyl-5,6,7,8-tetrahydronaphthalen-2-ol (CAS 56771-15-4), molecular formula C11H14O and molecular weight 162.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Methyl-5,6,7,8-tetrahydronaphthalen-2-ol (C11H14O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 162.23 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
