Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bisbenzimidazo2,1-a:1,2-banthra2,1,9-def:6,5,10-defdiisoquinoline-6,11-dione(mixture with trans-isomer) (CAS 55034-81-6), molecular formula C36H18N4O2 and molecular weight 538.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Bisbenzimidazo2,1-a:1,2-banthra2,1,9-def:6,5,10-defdiisoquinoline-6,11-dione(mixture with trans-isomer) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.55 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.
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.
