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 3-(4-Iodophenyl)-5-methyl-1h-1,2,4-triazole.
3-(4-Iodophenyl)-5-methyl-1h-1,2,4-triazole (CAS 1152849-82-5), molecular formula C9H8IN3 and molecular weight 285.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Iodophenyl)-5-methyl-1h-1,2,4-triazole (C9H8IN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. 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. 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-Iodophenyl)-5-methyl-1h-1,2,4-triazole 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.
