Chemical Structure

(Methyldiphenylsilyl)acetylene CAS 17156-65-9 chemical structure

Description

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 supplies (Methyldiphenylsilyl)acetylene (CAS 17156-65-9), a certified reference material (molecular formula C15H14Si, MW 222.36 g/mol) for analytical method development and quality control.

Structurally, (Methyldiphenylsilyl)acetylene (C15H14Si) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 222.36 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures (Methyldiphenylsilyl)acetylene 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.
