Chemical Structure

ethyl 4-aminocinnoline-3-carboxylate CAS 206002-69-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 227.30 g/mol gives ethyl 4-aminocinnoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies ethyl 4-aminocinnoline-3-carboxylate (CAS 206002-69-9), a certified reference material (molecular formula C11H21N3O2, MW 227.30 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, ethyl 4-aminocinnoline-3-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
