Compared with other compounds in its class, the molecular weight of 654.59 g/mol gives Bromocriptine EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bromocriptine EP Impurity C (CAS 65700-36-9) is a certified pharmaceutical impurity reference standard with the molecular formula C32H40BrN5O5 and a molecular weight of 654.59 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Bromocriptine EP Impurity C is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 654.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
