Chemical Structure
Description
Based on its molecular formula C19H35ClO2Si2, 1-(Chloromethyl)-3,5-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]benzene contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 387.10 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.
1-(Chloromethyl)-3,5-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]benzene (CAS 103929-85-7) is a high-purity analytical reference standard with the molecular formula C19H35ClO2Si2 and a molecular weight of 387.10 g/mol.
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.
