Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,3-Dimethyl-1-[3-methyl-4-(propan-2-yl)phenyl]urea (CAS 79473-12-4), molecular formula C13H20N2O and molecular weight 220.31 g/mol, is a CATO reference standard with documented purity and traceability.
3,3-Dimethyl-1-[3-methyl-4-(propan-2-yl)phenyl]urea (C13H20N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
