(R)-2-Amino-3-((((R)-2-oxotetrahydrofuran-3-yl)methyl)thio)propanoic acid CAS 138605-01-3

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-((((R)-2-oxotetrahydrofuran-3-yl)methyl)thio)propanoic acid.

(R)-2-Amino-3-((((R)-2-oxotetrahydrofuran-3-yl)methyl)thio)propanoic acid (CAS 138605-01-3), molecular formula C8H13NO4S and molecular weight 219.26 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H13NO4S, (R)-2-Amino-3-((((R)-2-oxotetrahydrofuran-3-yl)methyl)thio)propanoic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 219.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
