Chemical Structure

2-selenoxopropanoic acid CAS 919117-51-4 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-selenoxopropanoic acid.

2-selenoxopropanoic acid (CAS 919117-51-4) is a high-purity analytical reference standard with the molecular formula C3H4O2Se and a molecular weight of 151.02 g/mol.

Based on its molecular formula C3H4O2Se, 2-selenoxopropanoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 151.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
