Chemical Structure

Methyl Quinoline-8-carboxylate CAS 40245-26-9 chemical structure

Description

As a certified reference material (CRM), Methyl Quinoline-8-carboxylate 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.

Methyl Quinoline-8-carboxylate (CAS 40245-26-9) is a high-purity analytical reference standard with the molecular formula C11H9NO2 and a molecular weight of 187.19 g/mol.

The molecular framework of Methyl Quinoline-8-carboxylate (C11H9NO2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
