Quantitative determination of hydroxylamine

Talanta, 1974
This 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, 1957
Abstract 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, 1987
The 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 ...

Hydroxylamines and Hemolytic Anemia

1986
Hemolytic 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, 1949
IN 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.
