yksidiodisen

Yksidiodisen is a Finnish adjective used in chemistry to describe molecules that contain a single iodine substituent. In practice, a compound described as yksidiodinen is monoiodinated, meaning there is exactly one iodine atom attached to the molecular framework. The term helps distinguish such compounds from diodinated or polyiodinated substances, which contain two or more iodine atoms.

Etymology and formation: the word is formed from the numerals and roots taiped as yksi (one) and jodi (iodine) with the common chemical suffix -inen, which yields an adjective meaning iodinated of a single iodine. The form yksidiodisen appears in contexts requiring the genitive singular of the adjective, for example before a noun such as yksidiodisen yhdisteen (of a monoiodinated compound).

Usage and context: yksidiodisen is predominantly used in organic chemistry, medicinal chemistry, and radiochemistry when describing synthesis targets, reaction intermediates, or labeling strategies. It is common in descriptions of mono-iodinated aromatic rings, mono-iodinated peptides, or radiolabeled tracers where the presence of only one iodine atom is significant for properties such as reactivity, mass, or imaging behavior. The term can appear in research articles, theses, and technical reports where precise iodination level affects interpretation of results.

Related terms include diodinen (two iodine atoms) and polyiodinen (three or more iodine atoms), which serve to specify higher degrees of iodination. Yksidiodisen is thus a versatile descriptor for single-iodine substitution in Finnish chemical literature.
