Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 4-ethyl-5-imino-3-methyl-2,5-dihydro-1H-pyrazole-1-carbodithioate (CAS 342411-69-2) is a high-purity analytical reference standard with the molecular formula C8H13N3S2 and a molecular weight of 215.34 g/mol.
The molecular framework of Methyl 4-ethyl-5-imino-3-methyl-2,5-dihydro-1H-pyrazole-1-carbodithioate (C8H13N3S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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), Methyl 4-ethyl-5-imino-3-methyl-2,5-dihydro-1H-pyrazole-1-carbodithioate 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.
