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 meso-Tetra(2-nitrophenyl) porphine.
meso-Tetra(2-nitrophenyl) porphine (CAS 37116-82-8) is a high-purity analytical reference standard with the molecular formula C44H26N8O8 and a molecular weight of 794.73 g/mol.
Structurally, meso-Tetra(2-nitrophenyl) porphine (C44H26N8O8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 36.0, corresponding to approximately 36 ring(s) or double-bond equivalent(s). With a molecular weight of 794.73 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
