3-Dodecyl-1,1,1,3,5,5,5-heptamethyltrisiloxane CAS 139614-44-1

Description

3-Dodecyl-1,1,1,3,5,5,5-heptamethyltrisiloxane (C19H46O2Si3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

3-Dodecyl-1,1,1,3,5,5,5-heptamethyltrisiloxane (CAS 139614-44-1), molecular formula C19H46O2Si3 and molecular weight 390.82 g/mol, is a CATO reference standard with documented purity and traceability.

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.

CATO manufactures 3-Dodecyl-1,1,1,3,5,5,5-heptamethyltrisiloxane 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.
