Chemical Structure

3-Methyl-2-(trimethylsilyl)pyridine CAS 13737-07-0 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.

3-Methyl-2-(trimethylsilyl)pyridine (CAS 13737-07-0) is a high-purity analytical reference standard with the molecular formula C9H15NSi and a molecular weight of 165.31 g/mol.

The molecular framework of 3-Methyl-2-(trimethylsilyl)pyridine (C9H15NSi) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures 3-Methyl-2-(trimethylsilyl)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.
