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 2,3-Diaminosuccinic acid.
2,3-Diaminosuccinic acid (CAS 921-52-8), molecular formula C4H8N2O4 and molecular weight 148.12 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H8N2O4, 2,3-Diaminosuccinic acid contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 148.12 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.
