Chemical Structure

4-Chloro-7-methoxyquinoline-3-carboxylic Acid CAS 852062-08-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 237.64 g/mol gives 4-Chloro-7-methoxyquinoline-3-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-7-methoxyquinoline-3-carboxylic Acid (CAS 852062-08-9) is a high-purity analytical reference standard with the molecular formula C11H8ClNO3 and a molecular weight of 237.64 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-7-methoxyquinoline-3-carboxylic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
