Hexamine crystal structure


Hexamethylene tetramine or hexamine is also used as a food additive as a preservative INS number Acidity p K a. Although the molecular shape defines a cage, no void space is available at the interior for binding other atoms or molecules, unlike crown ethers or larger cryptand structures. In other projects Wikimedia Commons. Subsequent studies have shown that large doses of hexamethylenetetramine provide some protection if taken before phosgene exposure but none if taken afterwards. This white crystalline compound is highly soluble in water and polar organic solvents. Its use had temporarily been reduced in the late s, due to adverse effects, particularly chemically-induced hemorrhagic cystitis in overdose, [8] but its use has now been re-approved because of the prevalence of antibiotic resistance to more commonly used drugs. It decomposes at an acidic pH to form formaldehyde and ammoniaand the formaldehyde is bactericidal; the mandelic acid adds to this effect. Chemical formula.
