Bendamustine Nitro Ethyl Ester Impurity CAS 3543-72-4

Description

The occurrence of Bendamustine Nitro Ethyl Ester Impurity is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Bendamustine Nitro Ethyl Ester Impurity (CAS 3543-72-4) is a certified pharmaceutical impurity reference standard with the molecular formula C14H17N3O4 and a molecular weight of 291.30 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Bendamustine Nitro Ethyl Ester Impurity is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Bendamustine Nitro Ethyl Ester Impurity 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.
