(SP-5-12)-Chloro[[2,2′,2′′,2′′′-(21H,23H-porphine-5,10,15,20-tetrayl-κN21,κN22,κN23,κN24)tetrakis[phenolato]](2-)]iron CAS 900149-20-4

Description

As a certified reference material (CRM), (SP-5-12)-Chloro[[2,2′,2′′,2′′′-(21H,23H-porphine-5,10,15,20-tetrayl-κN21,κN22,κN23,κN24)tetrakis[phenolato]](2-)]iron meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(SP-5-12)-Chloro[[2,2′,2′′,2′′′-(21H,23H-porphine-5,10,15,20-tetrayl-κN21,κN22,κN23,κN24)tetrakis[phenolato]](2-)]iron (CAS 900149-20-4), molecular formula C44H28ClFeN4O4 and molecular weight 768.02 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (SP-5-12)-Chloro[[2,2′,2′′,2′′′-(21H,23H-porphine-5,10,15,20-tetrayl-κN21,κN22,κN23,κN24)tetrakis[phenolato]](2-)]iron is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 768.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
