Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 474.91 g/mol gives LX-2343 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
LX-2343 (CAS 333745-53-2) is a high-purity analytical reference standard with the molecular formula C22H19ClN2O6S and a molecular weight of 474.91 g/mol.
Based on its molecular formula C22H19ClN2O6S, LX-2343 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 474.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
