Chemical Structure
Description
2,4-Dichloro-5-Iodo-7-Methyl-7H-Pyrrolo[2,3-D]Pyrimidine (C7H4Cl2IN3) contains a nitrile group, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2,4-Dichloro-5-Iodo-7-Methyl-7H-Pyrrolo[2,3-D]Pyrimidine (CAS 2007910-59-8), molecular formula C7H4Cl2IN3 and molecular weight 327.94 g/mol, is a CATO reference standard with documented purity and traceability.
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.
