3,5-Bis((trimethylsilyl)ethynyl)pyridine CAS 267244-88-2

Description

Compared with other compounds in its class, the molecular weight of 271.50 g/mol gives 3,5-Bis((trimethylsilyl)ethynyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,5-Bis((trimethylsilyl)ethynyl)pyridine (CAS 267244-88-2), a certified reference material (molecular formula C15H21NSi2, MW 271.50 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H21NSi2, 3,5-Bis((trimethylsilyl)ethynyl)pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 3,5-Bis((trimethylsilyl)ethynyl)pyridine 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.
