Chemical Structure

4-Oxo-4-(pyridin-3-ylamino)butanoic acid CAS 25604-13-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 194.19 g/mol gives 4-Oxo-4-(pyridin-3-ylamino)butanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Oxo-4-(pyridin-3-ylamino)butanoic acid (CAS 25604-13-1), molecular formula C9H10N2O3 and molecular weight 194.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Oxo-4-(pyridin-3-ylamino)butanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
