Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-1-(2-methoxyphenyl)-2,2-dimethylpropane-1,3-diol.
(S)-1-(2-methoxyphenyl)-2,2-dimethylpropane-1,3-diol (CAS 167255-27-8) is a high-purity analytical reference standard with the molecular formula C12H18O3 and a molecular weight of 210.27 g/mol.
(S)-1-(2-methoxyphenyl)-2,2-dimethylpropane-1,3-diol (C12H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
