Comparative metabolism of hydantoin and beta-methyl hydantoin.
Experimental Biology and Medicine, 1926 In previous experiments1 it was pointed out that when betamethyl hydantoin is given subcutaneously to dogs only fifteen per cent of the compound reappears unchanged in the urine. A similar amount is excreted as methyl hydantoic acid. But while all of the nitrogen of the compound was excreted, the remainder was unaccounted for in the nitrogen partition.

New route for 1-substituted hydantoins [PDF]
, 1965 Alkytation reactions on hydantoins (I) lead smoothly to 3-alkyl derivatives; more rigorous conditions allow further substitution at position 1 provided the N1-H group is activated by an aryl group or an ethylenic bond attached to the adjacent C52,a.

Contact Dermatitis, Volume 95, Issue 2, Page 125-147, August 2026.ABSTRACT Formaldehyde and its releasers are common preservatives and potent sensitizers. This meta‐analysis aimed to estimate the prevalence of formaldehyde contact allergy and allergy to its five most common releasers among dermatitis patients. Two authors independently searched PubMed, Embase, and Web of Science from inception to 30th September 2025.
