Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3,4-dimethylphenyl)-1-(2-phenyl-4-(p-tolylthio)-1H-imidazol-5-yl)methanimine.
N-(3,4-dimethylphenyl)-1-(2-phenyl-4-(p-tolylthio)-1H-imidazol-5-yl)methanimine (CAS 303986-88-1), molecular formula C25H23N3S and molecular weight 397.54 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(3,4-dimethylphenyl)-1-(2-phenyl-4-(p-tolylthio)-1H-imidazol-5-yl)methanimine (C25H23N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 397.54 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-(3,4-dimethylphenyl)-1-(2-phenyl-4-(p-tolylthio)-1H-imidazol-5-yl)methanimine 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.
