Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lovastatin Impurity 21.
As a process- or degradation-related impurity, Lovastatin Impurity 21 (CAS CATO-C4X-168421, C18H39NC2H6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to an organic framework, Lovastatin Impurity 21 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.59 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.
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.
