Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 748.94 g/mol gives Erythromycin thiocyanate impurity C reduced derivative distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Erythromycin thiocyanate impurity C reduced derivative (CAS CATO-C4X-100167) is a certified pharmaceutical impurity reference standard with the molecular formula C37H68N2O13 and a molecular weight of 748.94 g/mol.
Erythromycin thiocyanate impurity C reduced derivative (C37H68N2O13) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Erythromycin thiocyanate impurity C reduced derivative 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.
