Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
5356-84-3 1,1,1,5,5,5-Hexamethyl-3-((trimethylsilyl)oxy)-3-vinyltrisiloxane Trisiloxane, 3-ethenyl-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)- EINECS 226-342-2 (CAS 5356-84-3), molecular formula C11H30O3Si4 and molecular weight 322.70 g/mol, is a CATO reference standard with documented purity and traceability.
5356-84-3 1,1,1,5,5,5-Hexamethyl-3-((trimethylsilyl)oxy)-3-vinyltrisiloxane Trisiloxane, 3-ethenyl-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)- EINECS 226-342-2 (C11H30O3Si4) 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.
CATO manufactures 5356-84-3 1,1,1,5,5,5-Hexamethyl-3-((trimethylsilyl)oxy)-3-vinyltrisiloxane Trisiloxane, 3-ethenyl-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)- EINECS 226-342-2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
