Chemical Structure

N-Cyano-N′-(2-mercaptoethyl)-N′′-methylguanidine CAS 61085-25-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N-Cyano-N′-(2-mercaptoethyl)-N′′-methylguanidine (CAS 61085-25-4) is a high-purity analytical reference standard with the molecular formula C5H10N4S and a molecular weight of 158.22 g/mol.

The molecular framework of N-Cyano-N′-(2-mercaptoethyl)-N′′-methylguanidine (C5H10N4S) is characterized by a nitrile group, sulfur-containing functionality. 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 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).

As a certified reference material (CRM), N-Cyano-N′-(2-mercaptoethyl)-N′′-methylguanidine 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.
