Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,8,12,18-Tetraethyl-3,7,13,17-tetramethyl-21H,23H-porphine.
2,8,12,18-Tetraethyl-3,7,13,17-tetramethyl-21H,23H-porphine (CAS 448-70-4), molecular formula C32H38N4 and molecular weight 478.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,8,12,18-Tetraethyl-3,7,13,17-tetramethyl-21H,23H-porphine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 478.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 2,8,12,18-Tetraethyl-3,7,13,17-tetramethyl-21H,23H-porphine 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.
