Chemical Structure

Lidocaine Impurity 40 CAS CATO-C4X-167940 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Lidocaine Impurity 40 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 230.31 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.

Lidocaine Impurity 40 (CAS CATO-C4X-167940) is a certified pharmaceutical impurity reference standard with the molecular formula C14H18N2O and a molecular weight of 230.31 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), Lidocaine Impurity 40 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.
