Nabumetone Impurity 11 CAS CATO-C4X-284811

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nabumetone Impurity 11.

Nabumetone Impurity 11 (CAS CATO-C4X-284811) is a certified pharmaceutical impurity reference standard with the molecular formula C18H16O2 and a molecular weight of 264.32 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Nabumetone Impurity 11 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.32 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.

CATO manufactures Nabumetone Impurity 11 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
