Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Diiodo-4,5-dimethylbenzene.
CATO supplies 1,2-Diiodo-4,5-dimethylbenzene (CAS 5182-67-2), a certified reference material (molecular formula C8H8I2, MW 357.96 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Diiodo-4,5-dimethylbenzene (C8H8I2) is characterized by iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
CATO manufactures 1,2-Diiodo-4,5-dimethylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
