ChemInform Abstract: CYANAMIDE DERIVATIVES. PART 99. ELECTROLYTIC OXIDATION OF CYANAMIDE [PDF]

open access: yesChemischer Informationsdienst, 1976
Abstract Cyanamide was electrochemically oxidized with a platinum anode in aqueous potassium hydroxide. Electrolysis was carried out at 1.30 V vs. SCE of anode potential. Oxidation products consist of several unknown 1,2,3,5-tetrazine compounds and known linear cyano compounds.

Role of aldehyde dehydrogenase in hypoxic vasodilator effects of nitrite in rats and humans [PDF]

open access: yes, 2015
Hypoxic conditions favour the reduction of nitrite to nitric oxide (NO) to elicit vasodilatation, but the mechanism(s) responsible for bioconversion remains ill defined.

Grapevines to Hydrogen Cyanamide [PDF]

open access: yesHortTechnology, 1999
The effects of surfactants on the efficacy of hydrogen cyanamide (H2CN2) applied to `Perlette' grapevines (Vitis vinifera L.) grown in the Coachella Valley of California were examined in 1994 and 1995. Vines were pruned in mid-December in both years and treatments applied at 1000 L·ha-1 the following day to dormant spurs and cordons using a hand-held ...
