A radioisotope labeled reagent includes a compound having the general formula (I) where a in each occurrence independently is a carbon mass number between 11 and 14 inclusive, b in each occurrence independently is a hydrogen mass number between 1 and 3 inclusive, such that a in each occurrence is not 12 simultaneously with b in each occurrence being 1; L is a leaving group R1SO2-O- , R1 -S-, 12C1H3(12C1 H2)n-S-R1C(O)O-, NC-, (R1)3P-, XMg- and Li-, where n is an integer between 0 and 3 inclusive, where X is chloro, bromo or iodine, where R1 is H, aryl, a substituent containing aryl, C1-C20 alkyl, a substituent containing C1-C20 alkyl, C2-C20 alkenyl, a substituent containing C2-C20 alkenyl, C2-C20 alkynyl, and a substitute containing C2-C20 alkynyl with the proviso that when n is 0, a is 13 and b is 2 and R1 in R1-S is not aryl.

L'invention concerne un réactif marqué par un radio-isotope, contenant un composé de formule générale : (I), dans laquelle a représente indépendamment dans chaque occurrence un nombre de masse de carbone compris entre 11 et 14 inclus ; b représente indépendamment dans chaque occurrence un nombre de masse d'hydrogène compris entre 1 et 3 inclus, de sorte que a dans chaque occurrence ne représente pas 12 simultanément avec b représentant 1 dans chaque occurrence ; L représente un groupe partant R?1¿SO¿2?-O-, R?1¿-S-, ?12¿C?1¿H¿3?(?12¿C?1¿H¿2?)¿n?-S-R?1¿C(O)O-, NC-, (R?1¿)¿3?P-, XMg- et Li-, dans lequel n représente un nombre entier compris entre 0 et 3 inclus, X représente chloro, bromo ou iode, R?1 ¿représente H, aryle, un substituant contenant aryle, alkyle C¿1?-C¿20?, un substituant contenant alkyle C¿1?-C¿20?, alcényle C¿2?-C¿20?, un substituant contenant alcényle C¿2?-C¿20?, alkynyle C¿2?-C¿20?, et un substituant contenant alkynyle C¿2?-C¿20?, à condition que, lorsque n représente 0, a représente 13 et b représente 2, et que R?1¿ dans R?1¿-S ne représente pas aryle.
