Chemical Structure
Description
As a certified reference material (CRM), meso-Tetraspiro[21H,23H-porphine-5(15H),1':10(22H),1'':15,1''':20(24H),1''''-tetrakiscyclohexane] 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.
meso-Tetraspiro[21H,23H-porphine-5(15H),1':10(22H),1'':15,1''':20(24H),1''''-tetrakiscyclohexane] (CAS 35320-70-8), molecular formula C40H52N4 and molecular weight 588.87 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, meso-Tetraspiro[21H,23H-porphine-5(15H),1':10(22H),1'':15,1''':20(24H),1''''-tetrakiscyclohexane] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 588.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
