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 1-[(3S,6S)-6-[(Benzenesulfonyl)oxy]-hexahydrofuro[3,2-b]furan-3-yl]-1H-1,2,3-triazole-4,5-dicarboxylic acid.
1-[(3S,6S)-6-[(Benzenesulfonyl)oxy]-hexahydrofuro[3,2-b]furan-3-yl]-1H-1,2,3-triazole-4,5-dicarboxylic acid (CAS 1276015-72-5), molecular formula C16H15N3O9S and molecular weight 425.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H15N3O9S, 1-[(3S,6S)-6-[(Benzenesulfonyl)oxy]-hexahydrofuro[3,2-b]furan-3-yl]-1H-1,2,3-triazole-4,5-dicarboxylic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 425.37 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.
