L-Histidine, 2,5-diiodo- is a chemical compound with the molecular formula C6H7I2N3O2. It is a derivative of the amino acid L-histidine, where two iodine atoms are attached to the 2nd and 5th positions of the imidazole ring. This modification can significantly alter the properties and reactivity of the original amino acid. L-Histidine, 2,5-diiodo- is used in various applications, including pharmaceutical research, as a building block for the synthesis of complex molecules, and in the study of protein structure and function. Its unique structure with iodine atoms can also be exploited for imaging purposes in medical diagnostics, such as in radioiodination techniques.

6996-16-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6996-16-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6996-16:
(6*6)+(5*9)+(4*9)+(3*6)+(2*1)+(1*6)=143
143 % 10 = 3
So 6996-16-3 is a valid CAS Registry Number.

Proprietes physico-chimiques des iodohistidines. I. Etude protometrique de la complexation des cations metalliques Cu(II), Co(II), Ni(II), Cd(II), Zn(II) par la mono- et la diiodohistidine

Physicochemical properties of iodo-histidines.I.Protometric study of the complexation of metallic cations Cu(II), Co(II), Ni(II), Cd(II), Zn(II) by mono- and diiodohistidine.Mono- (MIH) et diiodo- (DIH) histidines are synthesized by iodination of histidine using ICl; their protonation contants are determined at 25 deg C in 0,5 mol*L-1 NaNO3 (or NaCl) together with the stability constants of their complexes formed with ions of the first transition series.Computer refinement of the stability constant values was done by adjusting the calculated and experimental curves of neutralization by the PROTAF program.This work provides evidence for a variety of complexes.Apart from simple complexes, such as MA and MA2, other protonated or deprotonated species, like MHA and MH2A or MH-1A and MH-2A, were formed depending on the system. histidine / monoiodohistidine /diiodohistidine / cobalt / complexes / protometry
