((4-((4-Methoxyphenyl)ethynyl)phenyl)ethynyl)trimethylsilane CAS 787617-56-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((4-((4-Methoxyphenyl)ethynyl)phenyl)ethynyl)trimethylsilane.

((4-((4-Methoxyphenyl)ethynyl)phenyl)ethynyl)trimethylsilane (CAS 787617-56-5) is a high-purity analytical reference standard with the molecular formula C20H20OSi and a molecular weight of 304.46 g/mol.

Structurally, ((4-((4-Methoxyphenyl)ethynyl)phenyl)ethynyl)trimethylsilane (C20H20OSi) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 304.46 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 manufactures ((4-((4-Methoxyphenyl)ethynyl)phenyl)ethynyl)trimethylsilane 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.
