Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-2-Amino-3-(2-propynylthio)propanoic Acid.
(R)-2-Amino-3-(2-propynylthio)propanoic Acid (CAS 3262-64-4), molecular formula C6H9NO2S and molecular weight 159.21 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-2-Amino-3-(2-propynylthio)propanoic Acid (C6H9NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
