Chemical Structure

Lisdexamfetamine Impurity 3 CAS CATO-C4X-34623 chemical structure

Description

Lisdexamfetamine Impurity 3 (CAS CATO-C4X-34623) is a certified pharmaceutical impurity reference standard with the molecular formula C3H8NO3P and a molecular weight of 137.07 g/mol.

Structurally, Lisdexamfetamine Impurity 3 (C3H8NO3P) contains an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 137.07 g/mol, it falls into the low-molecular-weight range. 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.
