Description
CATO manufactures Dimethylbis(phenylethynyl)silane 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.
Dimethylbis(phenylethynyl)silane (CAS 2170-08-3), molecular formula C18H16Si and molecular weight 260.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, Dimethylbis(phenylethynyl)silane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
