21H,23H-Porphine, 5,10,15,20-tetra-2-thienyl- CAS 22112-87-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 21H,23H-Porphine, 5,10,15,20-tetra-2-thienyl-.

21H,23H-Porphine, 5,10,15,20-tetra-2-thienyl- (CAS 22112-87-4) is a high-purity analytical reference standard with the molecular formula C36H22N4S4 and a molecular weight of 638.85 g/mol.

Structurally, 21H,23H-Porphine, 5,10,15,20-tetra-2-thienyl- (C36H22N4S4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 638.85 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 21H,23H-Porphine, 5,10,15,20-tetra-2-thienyl- 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.
