Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Cyclopropylquinoline-4-carboxylic Acid (CAS 119778-64-2) is a high-purity analytical reference standard with the molecular formula C13H11NO2H2O and a molecular weight of 231.25 g/mol.
The molecular framework of 2-Cyclopropylquinoline-4-carboxylic Acid (C13H11NO2H2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
As a certified reference material (CRM), 2-Cyclopropylquinoline-4-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.
