Chemical Structure

4,6-Bis(methylthio)cinnoline CAS 6959-40-6 chemical structure

Description

As a certified reference material (CRM), 4,6-Bis(methylthio)cinnoline 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.

CATO supplies 4,6-Bis(methylthio)cinnoline (CAS 6959-40-6), a certified reference material (molecular formula C10H10N2S2, MW 222.33 g/mol) for analytical method development and quality control.

Structurally, 4,6-Bis(methylthio)cinnoline (C10H10N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 222.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
