Chemical Structure
Description
The occurrence of 3-Methyl-4-(pyridin-2-yl)cinnoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Methyl-4-(pyridin-2-yl)cinnoline (CAS 817209-09-9), molecular formula C14H11N3 and molecular weight 221.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methyl-4-(pyridin-2-yl)cinnoline (C14H11N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 3-Methyl-4-(pyridin-2-yl)cinnoline 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.
