2734-52-3 2,2'-((4-((4-Nitrophenyl)azo)phenyl)imino)bisethanol Ethanol, 2,2'-((4-(2-(4-nitrophenyl)diazenyl)phenyl)imino)bis- Ethanol, 2,2'-((4-((4-nitrophenyl)azo)phenyl)imino)bis- C.I. Disperse Red 19 EINECS 220-354-1 NSC 364364 (CAS 2734-52-3), molecular formula C16H30N4O4 and molecular weight 342.43 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, 2734-52-3 2,2'-((4-((4-Nitrophenyl)azo)phenyl)imino)bisethanol Ethanol, 2,2'-((4-(2-(4-nitrophenyl)diazenyl)phenyl)imino)bis- Ethanol, 2,2'-((4-((4-nitrophenyl)azo)phenyl)imino)bis- C.I. Disperse Red 19 EINECS 220-354-1 NSC 364364 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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