Chemical Structure

(R)-Ethyl 2-acetamidobutanoate CAS 105500-33-2 chemical structure

Description

(R)-Ethyl 2-acetamidobutanoate (CAS 105500-33-2), molecular formula C8H15NO3 and molecular weight 173.21 g/mol, is a CATO reference standard with documented purity and traceability.

(R)-Ethyl 2-acetamidobutanoate (C8H15NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
