Chemical Structure

Penicillin G Sodium Salt CAS 69-57-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 356.37 g/mol gives Penicillin G Sodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Penicillin G Sodium Salt (CAS 69-57-8), molecular formula C16H17N2O4SNa and molecular weight 356.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Penicillin G Sodium Salt (C16H17N2O4SNa) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
