Chemical Structure

Lercanidipine Impurity 38 CAS 10317-10-9 chemical structure

Description

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.

Lercanidipine Impurity 38 (CAS 10317-10-9) is a certified pharmaceutical impurity reference standard with the molecular formula C4H9ClO and a molecular weight of 108.57 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, Lercanidipine Impurity 38 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
