Description
As a certified reference material (CRM), Methyl violet 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.
Methyl violet (CAS 1340-02-9) is a high-purity analytical reference standard with the molecular formula C37H58N2Na2O10S3C15H26N3NaO2 and a molecular weight of 1136.42 g/mol.
Based on its molecular formula C37H58N2Na2O10S3C15H26N3NaO2, Methyl violet contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1136.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
