Chemical Structure

Pramocaine Impurity 1 CAS 48152-09-6 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Pramocaine Impurity 1 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Pramocaine Impurity 1 (CAS 48152-09-6) is a certified pharmaceutical impurity reference standard with the molecular formula C11H22N2O2 and a molecular weight of 214.30 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.

As a certified reference material (CRM), Pramocaine Impurity 1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
