Chemical Structure
Description
The occurrence of (S)-2-Amino-N-(3-chloro-pyrazin-2-ylmethyl)-N-methyl-propionamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-Amino-N-(3-chloro-pyrazin-2-ylmethyl)-N-methyl-propionamide (CAS 1353993-33-5), molecular formula C9H12N4O2 and molecular weight 208.22 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-Amino-N-(3-chloro-pyrazin-2-ylmethyl)-N-methyl-propionamide (C9H12N4O2) 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.
