Chemical Structure
Description
CATO supplies Landiolol Impurity 29 (CAS CATO-C4X-262129), a pharmacopoeial impurity reference standard (molecular formula C22H35N3O8HCl, MW 505.99 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Landiolol Impurity 29 (C22H35N3O8HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 505.99 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
