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 L-Ornithine L-Aspartate Impurity 19.
CATO supplies L-Ornithine L-Aspartate Impurity 19 (CAS 60259-82-7), a pharmacopoeial impurity reference standard (molecular formula C10H22N4O3, MW 246.31 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, L-Ornithine L-Aspartate Impurity 19 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.31 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.
As a certified reference material (CRM), L-Ornithine L-Aspartate Impurity 19 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.
