Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1,1,1-Trichloro-5,8,11,14-tetraoxa-1-silapentadecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1,1,1-Trichloro-5,8,11,14-tetraoxa-1-silapentadecane (CAS 228700-87-6), molecular formula C10H21Cl3O4Si and molecular weight 339.72 g/mol, is a CATO reference standard with documented purity and traceability.
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.
