Ketorolac Impurity 24 CAS 141054-41-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ketorolac Impurity 24.

Ketorolac Impurity 24 (CAS 141054-41-3) is a certified pharmaceutical impurity reference standard with the molecular formula C15H15NO3 and a molecular weight of 257.28 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ketorolac Impurity 24 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
