Chemical Structure

Oxeladin Hydrogen Citrate EP Impurity A CAS 140-82-9 chemical structure

Description

The occurrence of Oxeladin Hydrogen Citrate EP Impurity A is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Oxeladin Hydrogen Citrate EP Impurity A (CAS 140-82-9, C8H19NO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Oxeladin Hydrogen Citrate EP Impurity A is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.24 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), Oxeladin Hydrogen Citrate EP Impurity A 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.
