Chemical Structure
Description
The occurrence of Bromocriptine EP Impurity D TFA Salt is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Bromocriptine EP Impurity D TFA Salt (CAS CATO-C4X-136110), a pharmacopoeial impurity reference standard (molecular formula C16H15BrN2O2C2HF3O2, MW 461.23 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Bromocriptine EP Impurity D TFA Salt (C16H15BrN2O2C2HF3O2) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Bromocriptine EP Impurity D TFA Salt 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.
