Description
CATO manufactures Benzene, (trichlorosilyl)-, polymer with dichlorodimethylsilane and trichloromethylsilane 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.
Benzene, (trichlorosilyl)-, polymer with dichlorodimethylsilane and trichloromethylsilane (CAS 25766-16-9) is a high-purity analytical reference standard with the molecular formula C6H5Cl3SiCH3Cl3SiC2H6Cl2Si and a molecular weight of 490.07 g/mol.
Owing to chlorine substitution, Benzene, (trichlorosilyl)-, polymer with dichlorodimethylsilane and trichloromethylsilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 490.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
