Description
28265-17-0 KS-000018JD Manganese,chloro[2,3,7,8,12,13,17,18-octaethyl-21H,23H-porphinato(2-)-kN21,kN22kN23,kN24]-, (SP-5-12)- (CAS 28265-17-0), molecular formula C36H66ClMnN4 and molecular weight 645.33 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 28265-17-0 KS-000018JD Manganese,chloro[2,3,7,8,12,13,17,18-octaethyl-21H,23H-porphinato(2-)-kN21,kN22kN23,kN24]-, (SP-5-12)- (C36H66ClMnN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 645.33 g/mol, it falls into the high-molecular-weight range. 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.
