Chemical Structure
Description
The molecular framework of 2-Chloro-5-methyl-3-(trimethylsilyl)pyridine (C9H14ClNSi) is characterized by a nitrile group, chlorine substitution. 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. 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).
2-Chloro-5-methyl-3-(trimethylsilyl)pyridine (CAS 1203498-92-3) is a high-purity analytical reference standard with the molecular formula C9H14ClNSi and a molecular weight of 199.75 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Chloro-5-methyl-3-(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.
