Norethisterone Acetate EP Impurity F CAS 6856-27-5

Description

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

As a process- or degradation-related impurity, Norethisterone Acetate EP Impurity F (CAS 6856-27-5, C22H28O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Norethisterone Acetate EP Impurity F is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.46 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.

As a certified reference material (CRM), Norethisterone Acetate EP Impurity F 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.
