Chemical Structure
Description
4-chloro-6-iodo-pyrimidine (CAS 258506-74-0), molecular formula C4H8ClIN2 and molecular weight 246.48 g/mol, is a CATO reference standard with documented purity and traceability.
4-chloro-6-iodo-pyrimidine (C4H8ClIN2) contains chlorine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 4-chloro-6-iodo-pyrimidine 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.
