Hydroxylamine as an amnestic agent
Agents and Actions, 1972Intracranial injection of 0.5 M hydroxylamine causes long lasting amnesia even when injected three weeks after training of passive avoidance task, alimentary conditioning or discrimination in water maze. Other functions of the brain and new learning are not affected. There is no spontaneous return of the erased memory.

Quantitative determination of hydroxylamine
Talanta, 1974This paper is a survey of 66 studies from the literature and presents a review of the quantitative methods most widely used for the determination of hydroxylamine and its salts. Volumetric, electrochemical and spectrophotometric methods are discussed, compared and evaluated.

Hydroxylamine and reactive acyls
Archives of Biochemistry and Biophysics, 1957Abstract Conditions for the selective and complete reactivity of thiol esters with hydroxylamine are described, and conditions hazardous to the successful isolation of hydroxamates are presented. The R f values of a series of biological compounds are tabulated.

Decomposition of hydroxylamine by hemoglobin
Archives of Biochemistry and Biophysics, 1987The reaction between hydroxylamine (NH2OH) and human hemoglobin (Hb) at pH 6-8 and the reaction between NH2OH and methemoglobin (Hb+) chiefly at pH 7 were studied under anaerobic conditions at 25 degrees C. In presence of cyanide, which was used to trap Hb+, Hb was oxidized by NH2OH to methemoglobin cyanide with production of about 0.5 mol NH+4/mol of ...

Electrochemical Synthesis of Hydroxylamine
Angewandte Chemie International EditionAbstract Hydroxylamine (NH 2 OH) serves as an important industrial feedstock. The conventional production and transportation of NH 2 OH requires harsh conditions. Recently, electrochemical hydrogenation of nitrogen‐containing oxidative

Hydroxylamines and Hemolytic Anemia
1986Hemolytic anemia, the uncompensated loss of red blood cells from the circulation, has been recognized as a side effect of drugs and other chemicals for over 50 years (Muelens, 1926; Cordes, 1926). This response is commonly associated with the aminoquinoline drugs, pamaquine and primaquine (Beutler, 1959); indeed the extensive studies carried out with ...

Hydroxylamine Assay of Penicillin
Nature, 1949IN order to obtain a satisfactory chemical method for the determination of penicillin which might be applied throughout the penicillin production process from fermenter broth to final product, the hydroxylamine method of Staab, Ragan and Binkley1, which was modified by Ford2 to include the assay of broth, was investigated in these laboratories.
