Chemical Structure

羟氯喹杂质11 CAS 478784-66-6 chemical structure

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 羟氯喹杂质11 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.43 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, 羟氯喹杂质11 (CAS 478784-66-6, C18H27N3O) 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 羟氯喹杂质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.
