Chemical Structure

Pramocaine Impurity 2 CAS 125422-83-5 chemical structure

Description

The occurrence of Pramocaine Impurity 2 is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pramocaine Impurity 2 (CAS 125422-83-5) is a certified pharmaceutical impurity reference standard with the molecular formula C7H14BrNO and a molecular weight of 208.10 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, Pramocaine Impurity 2 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
