Chemical Structure

Phentolamine Mesilate Impurity 6 CAS 13338-49-3 chemical structure

Description

Phentolamine Mesilate Impurity 6 (C4H7ClN2HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Phentolamine Mesilate Impurity 6 (CAS 13338-49-3) is a certified pharmaceutical impurity reference standard with the molecular formula C4H7ClN2HCl and a molecular weight of 155.02 g/mol.

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.
