3346-23-4 4-quinolinecarboxylic acid, 2-hydroxy-6-methyl- AR-1G4592 CAS 3346-23-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3346-23-4 4-quinolinecarboxylic acid, 2-hydroxy-6-methyl- AR-1G4592.

3346-23-4 4-quinolinecarboxylic acid, 2-hydroxy-6-methyl- AR-1G4592 (CAS 3346-23-4), molecular formula C4H5N5O3 and molecular weight 171.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3346-23-4 4-quinolinecarboxylic acid, 2-hydroxy-6-methyl- AR-1G4592 (C4H5N5O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
