Chemical Structure

Maribavir Impurity 37 CAS CATO-C4X-300737 chemical structure

Description

The occurrence of Maribavir Impurity 37 is closely related to a nitrile group, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Maribavir Impurity 37 (CAS CATO-C4X-300737) is a certified pharmaceutical impurity reference standard with the molecular formula C7H3BrCl2N2 and a molecular weight of 265.92 g/mol.

Structurally, Maribavir Impurity 37 (C7H3BrCl2N2) contains a nitrile group, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 265.92 g/mol, it falls into the medium-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.

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.

As a certified reference material (CRM), Maribavir Impurity 37 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.
