Chemische Eigenschaften
white crystals
Verwenden
Usually used as template compound in the preparation of molecularly imprinted polymer via electropolymerization and electrodeposition of pyrrole on a pencil graphite electrode,and also used in the preparation of benzimidazolium surfactant, 1-hexadecyl-1H-benzimidazole.
Allgemeine Beschreibung
White tabular crystals.
Air & Water Reaktionen
Insoluble in water.
Reaktivit?t anzeigen
An amine. Neutralizes acids to form salts plus water. These acid-base reactions are exothermic. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. May be shock sensitive.
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition Benzimidazole emits highly toxic fumes.
Brandgefahr
Flash point data for Benzimidazole are not available. Benzimidazole is probably combustible.
Pharmakologie
The mode of action of benzimidazoles has been described
in several comprehensive reviews (1,32,33). The primary
mode of action of benzimidazoles has been identified as
the specific binding to the β-subunit of fungal tubulin and,
consequently, an interference with microtubule assembly.
Microtubules are major components of the fungal
cytoskeleton and are involved in meiosis and mitosis, both
of which are blocked in the presence of benzimidazoles.
Sicherheitsprofil
Poison by intravenous
and intraperitoneal routes. Moderately toxic
by ingestion. Mutation data reported. When
heated to decomposition it emits highly
toxic fumes of NOx.
l?uterung methode
It crystallises from water or aqueous EtOH (charcoal) and is dried at 100o for 12hours. [Beilstein 23 H 131, 23/6 V 196.]
