Chemical Structure
Description
The occurrence of Piperacillin Sodium Salt is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Piperacillin Sodium Salt (CAS 59703-84-3) is a high-purity analytical reference standard with the molecular formula C23H26N5O7SNa and a molecular weight of 539.54 g/mol.
Structurally, Piperacillin Sodium Salt (C23H26N5O7SNa) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.5, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 539.54 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Piperacillin Sodium Salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
