Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 457.36 g/mol gives Terbutaline Impurity 89 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Terbutaline Impurity 89 (CAS CATO-C4X-118389) is a certified pharmaceutical impurity reference standard with the molecular formula C24H25BrO4 and a molecular weight of 457.36 g/mol.
Structurally, Terbutaline Impurity 89 (C24H25BrO4) contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 457.36 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
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.
