Chemical Structure
Description
4-(tert-Butyldimethylsilyloxy)-3-methylaniline (CAS 309712-95-6) is a high-purity analytical reference standard with the molecular formula C13H23NOSi and a molecular weight of 237.41 g/mol.
Based on its molecular formula C13H23NOSi, 4-(tert-Butyldimethylsilyloxy)-3-methylaniline contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 237.41 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.
