Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 414.45 g/mol gives Sulbenicillin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sulbenicillin (CAS 41744-40-5) is a high-purity analytical reference standard with the molecular formula C16H18N2O7S2 and a molecular weight of 414.45 g/mol.
Sulbenicillin (C16H18N2O7S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
