Description
CATO manufactures 4-Bromo-6-iodo-5-methylpyrimidine 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.
CATO supplies 4-Bromo-6-iodo-5-methylpyrimidine (CAS 1805574-74-6), a certified reference material (molecular formula C5H4BrIN2, MW 298.91 g/mol) for analytical method development and quality control.
4-Bromo-6-iodo-5-methylpyrimidine (C5H4BrIN2) contains a nitrile group, bromine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
