Chemical Structure

Lodoxamide Impurity N44 CAS 14994-02-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lodoxamide Impurity N44.

CATO supplies Lodoxamide Impurity N44 (CAS 14994-02-6), a pharmacopoeial impurity reference standard (molecular formula C9H13NOSHCl, MW 219.73 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, Lodoxamide Impurity N44 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.73 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.

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), Lodoxamide Impurity N44 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.
