Chemical Structure

Relebactam Impurity 8 CAS CATO-C4X-21448 chemical structure

Description

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.

CATO supplies Relebactam Impurity 8 (CAS CATO-C4X-21448), a pharmacopoeial impurity reference standard (molecular formula C8H14C3H8CH4, MW 170.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Relebactam Impurity 8 (C8H14C3H8CH4) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 170.34 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
