The molecular framework of 623-26-7 E6ITH5CIS3 1,4-Dicyanobenzene 1,4-Benzenedicarbonitrile Terephthalonitrile 1,4-Benzendikarbonitril [Czech] p-Benzenedinitrile 1,4-Benzodinitrile 4-Cyanobenzonitrile p-Dicyanobenzene EINECS 210-783-2 Nitril kyseliny tereftalove [Czech] NSC 144977 NSC 78439 p-Pdn p-Phthalodinitrile Tereftalodinitril [Czech] Tereftalonitril [Czech] Terephthalic acid dinitrile Terephthalodinitril [German] Terephthalodinitrile 1,4-Benzendikarbonitril Nitril kyseliny tereftalove Tereftalodinitril Tereftalonitril Terephthalodinitril UNII-E6ITH5CIS3 (C8H10N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
