Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1'-Bis(2,4-dinitrophenyl)-4,4'-bipyridinium Dichloride.
1,1'-Bis(2,4-dinitrophenyl)-4,4'-bipyridinium Dichloride (CAS 41168-79-0) is a high-purity analytical reference standard with the molecular formula C22H14N6O8Cl and a molecular weight of 525.84 g/mol.
Structurally, 1,1'-Bis(2,4-dinitrophenyl)-4,4'-bipyridinium Dichloride (C22H14N6O8Cl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.5, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 525.84 g/mol, it falls into the moderately-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.
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.
