(SP-4-1)-[5,10,15,20-Tetrakis(4-bromophenyl)-21H,23H-porphinato(2-)-κN21,κN22,κN23,κN24]cobalt CAS 178476-63-6

Description

The occurrence of (SP-4-1)-[5,10,15,20-Tetrakis(4-bromophenyl)-21H,23H-porphinato(2-)-κN21,κN22,κN23,κN24]cobalt is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(SP-4-1)-[5,10,15,20-Tetrakis(4-bromophenyl)-21H,23H-porphinato(2-)-κN21,κN22,κN23,κN24]cobalt (CAS 178476-63-6), molecular formula C44H24Br4CoN4 and molecular weight 987.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, (SP-4-1)-[5,10,15,20-Tetrakis(4-bromophenyl)-21H,23H-porphinato(2-)-κN21,κN22,κN23,κN24]cobalt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 987.24 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.

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.
