Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 649.75 g/mol gives Rocuronium impurity 70 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Rocuronium impurity 70 (CAS CATO-C4X-124270, C35H57N2O4Br) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Rocuronium impurity 70 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 649.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Rocuronium impurity 70 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.
