Melarsomine Dihydrochloride CAS 89141-50-4

Description

Compared with other compounds in its class, the molecular weight of 464.87 g/mol gives Melarsomine Dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Melarsomine Dihydrochloride (CAS 89141-50-4), molecular formula C13H21AsN8S2HCl and molecular weight 464.87 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Melarsomine Dihydrochloride (C13H21AsN8S2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Melarsomine Dihydrochloride 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.
