Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Dichloro-N-((5-methyl-1H-imidazol-4-yl)methylene)aniline.
3,4-Dichloro-N-((5-methyl-1H-imidazol-4-yl)methylene)aniline (CAS 88634-81-5) is a high-purity analytical reference standard with the molecular formula C11H9Cl2N3 and a molecular weight of 254.12 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3,4-Dichloro-N-((5-methyl-1H-imidazol-4-yl)methylene)aniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3,4-Dichloro-N-((5-methyl-1H-imidazol-4-yl)methylene)aniline 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.
