Chemical Structure

Clavulanic acid Impurity 18 CAS 598-56-1 chemical structure

Description

The occurrence of Clavulanic acid Impurity 18 is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Clavulanic acid Impurity 18 (CAS 598-56-1), a pharmacopoeial impurity reference standard (molecular formula C4H11N, MW 73.14 g/mol) used for the identification and quantification of trace impurities in APIs.

Clavulanic acid Impurity 18 (C4H11N) contains an organic framework. Its physicochemical properties are representative of its class; 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
