61450-21-3
Butyl 5-oxo-DL-prolinate
EINECS 262-802-9 CAS 61450-21-3 chemical structure

Description

Based on its molecular formula C9H15NO3, 61450-21-3 Butyl 5-oxo-DL-prolinate EINECS 262-802-9 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 185.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

61450-21-3 Butyl 5-oxo-DL-prolinate EINECS 262-802-9 (CAS 61450-21-3), molecular formula C9H15NO3 and molecular weight 185.22 g/mol, is a CATO reference standard with documented purity and traceability.

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.
