Bisoprolol Impurity 74 (CAS 14435-48-4) is a certified pharmaceutical impurity reference standard with the molecular formula C8H16O3 and a molecular weight of 160.21 g/mol.
Structurally, Bisoprolol Impurity 74 (C8H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 160.21 g/mol, it falls into the medium-molecular-weight range.
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.
