Description
CATO manufactures 1,6-Dimethyl-1,1,2,2,3,3,4,4,5,5,6,6-dodecaphenylhexasilane 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.
1,6-Dimethyl-1,1,2,2,3,3,4,4,5,5,6,6-dodecaphenylhexasilane (CAS 1586-77-2) is a high-purity analytical reference standard with the molecular formula C74H66Si6 and a molecular weight of 1123.83 g/mol.
Owing to a polycyclic aromatic system, 1,6-Dimethyl-1,1,2,2,3,3,4,4,5,5,6,6-dodecaphenylhexasilane is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1123.83 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.
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.
