Chemical Structure
Description
The molecular framework of 7-Methyl-1,8-naphthyridine-2-carboxylic acid (C10H8N2O2) is characterized by an amino-acid-derived structure, an amide group, 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.
7-Methyl-1,8-naphthyridine-2-carboxylic acid (CAS 923689-18-3), molecular formula C10H8N2O2 and molecular weight 188.18 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Methyl-1,8-naphthyridine-2-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
