iodoso-prefix

Stress is usually determined by a subsequent element and vowels may be reduced accordingly. Some degree of stress is always maintained on the third syllable. If the subsequent element is an existing word, it is likely to retain its original stress pattern, e.g. iodosobenzene n. Brit.

/ʌɪəˌdəʊsə(ʊ)ˈbɛnziːn/,

/ʌɪəˌdəʊsə(ʊ)bɛnˈziːn/, U.S.

/ˌaɪəˌdoʊsoʊˈbɛnˌzin/,

/ˌaɪəˌdoʊsoʊˌbɛnˈzin/.

used in Chemistry as combining form of iodous adj. to indicate the presence of an IO group in a compound, as in iodosobenzene n. C₆H₅IO, a yellow amorphous powder which disproportionates to iodobenzene and iodoxybenzene, and explodes when heated. Also (without hyphen) as quasi-adj.
