Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, Amorolfine Impurity 44 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.52 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.
As a process- or degradation-related impurity, Amorolfine Impurity 44 (CAS CATO-C4X-154244, C22H36O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Amorolfine Impurity 44 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.
