Description
Compared with other compounds in its class, the molecular weight of 270.52 g/mol gives 1,1,2,2-Tetramethyl-1,2-diphenyldisilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,1,2,2-Tetramethyl-1,2-diphenyldisilane (CAS 1145-98-8) is a high-purity analytical reference standard with the molecular formula C16H22Si2 and a molecular weight of 270.52 g/mol.
The molecular framework of 1,1,2,2-Tetramethyl-1,2-diphenyldisilane (C16H22Si2) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1,1,2,2-Tetramethyl-1,2-diphenyldisilane 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.
