WebA completely pure sample of the aldehyde is readily obtained by stirring the crude aldehyde with excess saturated aqueous sodium bisulfite solution for several hours, filtering the solid bisulfite adduct, washing with ether, and liberating the aldehyde with excess aqueous sodium bicarbonate. WebIn 1970 two groups simultaneously described the reaction between pyrimidines and sodium bisulfate (NaHSO3, [37, 38]). They demonstrated that treatment of DNA with sodium bisulfite results in specific deamination of cytosine and conversion into uracil. Deamination of 5-methylcytosine occurred much slower compared to cytosine deamination.
