Letrozole Impurity 37 CAS 30132-90-2

Description

Compared with other compounds in its class, the molecular weight of 84.08 g/mol gives Letrozole Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Letrozole Impurity 37 (CAS 30132-90-2), a pharmacopoeial impurity reference standard (molecular formula C2H4N4, MW 84.08 g/mol) used for the identification and quantification of trace impurities in APIs.

Letrozole Impurity 37 (C2H4N4) contains a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Letrozole 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.
