Chemical Structure
Description
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.
5,10,15,20-Tetra(4-methylphenyl)-21H,23H-porphine iron(III) chloride (CAS 19496-18-5), molecular formula C50H42ClFeN4 and molecular weight 790.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5,10,15,20-Tetra(4-methylphenyl)-21H,23H-porphine iron(III) chloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 790.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 5,10,15,20-Tetra(4-methylphenyl)-21H,23H-porphine iron(III) chloride 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.
