Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 73.14 g/mol gives Potassium Clavulanate EP Impurity H distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Potassium Clavulanate EP Impurity H (CAS 75-64-9) is a certified pharmaceutical impurity reference standard with the molecular formula C4H11N and a molecular weight of 73.14 g/mol.
Owing to an organic framework, Potassium Clavulanate EP Impurity H is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 73.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
