sodium 4,4',4'',4'''-(porphyrin-5,10,15,20-tetrayl)tetrabenzenesulfonate do CAS 122451-08-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including sodium 4,4',4'',4'''-(porphyrin-5,10,15,20-tetrayl)tetrabenzenesulfonate do.

CATO supplies sodium 4,4',4'',4'''-(porphyrin-5,10,15,20-tetrayl)tetrabenzenesulfonate do (CAS 122451-08-5), a certified reference material (molecular formula C44H26N4O12S4NaH2O, MW 971.95 g/mol) for analytical method development and quality control.

Structurally, sodium 4,4',4'',4'''-(porphyrin-5,10,15,20-tetrayl)tetrabenzenesulfonate do (C44H26N4O12S4NaH2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 33.0, corresponding to approximately 33 ring(s) or double-bond equivalent(s). With a molecular weight of 971.95 g/mol, it falls into the high-molecular-weight range. 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.

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.
