Erythromycin thiocyanate impurity A reduced derivative CAS CATO-C4X-100168

Description

Compared with other compounds in its class, the molecular weight of 750.96 g/mol gives Erythromycin thiocyanate impurity A reduced derivative distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Erythromycin thiocyanate impurity A reduced derivative (CAS CATO-C4X-100168), a pharmacopoeial impurity reference standard (molecular formula C37H70N2O13, MW 750.96 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Erythromycin thiocyanate impurity A reduced derivative is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 750.96 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.

As a certified reference material (CRM), Erythromycin thiocyanate impurity A 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.
