Description

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.

58473-78-2 AR-1I2279 chromium(3+) sodium 3-(dioxidoamino)-5-[(3-methyl-5-oxo-1-phenyl-1,5-dihydro-4h-pyrazol-4-ylidene)hydrazinylidene]-6-oxocyclohexa-1,3-diene-1-sulfonate 5-methyl-4-[(3-nitro-6-oxocyclohexa-2,4-dien-1-ylidene)diazanidyl]-3-oxo-2-phenyl-2,3-dihydropyrazol-1-ide(1:2:1:1) (CAS 58473-78-2) is a high-purity analytical reference standard with the molecular formula C46H82N2 and a molecular weight of 663.16 g/mol.

Structurally, 58473-78-2 AR-1I2279 chromium(3+) sodium 3-(dioxidoamino)-5-[(3-methyl-5-oxo-1-phenyl-1,5-dihydro-4h-pyrazol-4-ylidene)hydrazinylidene]-6-oxocyclohexa-1,3-diene-1-sulfonate 5-methyl-4-[(3-nitro-6-oxocyclohexa-2,4-dien-1-ylidene)diazanidyl]-3-oxo-2-phenyl-2,3-dihydropyrazol-1-ide(1:2:1:1) (C46H82N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 663.16 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
