Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.28 g/mol gives 5-Acetyl-4-amino-6-methyl-2-(methylthio)nicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Acetyl-4-amino-6-methyl-2-(methylthio)nicotinonitrile (CAS 653587-91-8) is a high-purity analytical reference standard with the molecular formula C10H11N3OS and a molecular weight of 221.28 g/mol.
The molecular framework of 5-Acetyl-4-amino-6-methyl-2-(methylthio)nicotinonitrile (C10H11N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 5-Acetyl-4-amino-6-methyl-2-(methylthio)nicotinonitrile 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.
