Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 278.54 g/mol gives 4,4'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(butan-1-ol) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,4'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(butan-1-ol) (CAS 5931-17-9), a certified reference material (molecular formula C12H30O3Si2, MW 278.54 g/mol) for analytical method development and quality control.
4,4'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(butan-1-ol) (C12H30O3Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
