Chemical Structure
Description
3-Methyl-2-(methylsulfanyl)-5-(tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (CAS 918350-15-9) is a high-purity analytical reference standard with the molecular formula C13H15BCl2O3 and a molecular weight of 300.97 g/mol.
The molecular framework of 3-Methyl-2-(methylsulfanyl)-5-(tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (C13H15BCl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Methyl-2-(methylsulfanyl)-5-(tetramethyl-1,3,2-dioxaborolan-2-yl)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.
