Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 588.72 g/mol gives Penicillin G procaine hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Penicillin G procaine hydrate (CAS 6130-64-9), molecular formula C16H18N2O4SC13H20N2O2H2O and molecular weight 588.72 g/mol, is a CATO reference standard with documented purity and traceability.
Penicillin G procaine hydrate (C16H18N2O4SC13H20N2O2H2O) contains a nitrogen-containing heterocyclic scaffold, 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.
