Chemical Structure
Description
The occurrence of (5-tert-Butyl-2-phenylmethoxyphenyl)methanol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5-tert-Butyl-2-phenylmethoxyphenyl)methanol (CAS 1246213-25-1), molecular formula C18H22O2 and molecular weight 270.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H22O2, (5-tert-Butyl-2-phenylmethoxyphenyl)methanol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
