1-Propyne, 3-bromo-1-iodo, also known as 3-Bromo-1-iodopropyne or 3-Bromo-1-iodo-1-propyne, is a halogenated alkyne with the chemical formula C3H3BrI. It is a colorless liquid at room temperature and is characterized by the presence of a triple bond between the first and second carbon atoms, with a bromine atom attached to the third carbon and an iodine atom attached to the first carbon. 1-Propyne, 3-bromo-1-iodo- is primarily used as a chemical intermediate in the synthesis of various organic compounds, particularly in the pharmaceutical and agrochemical industries. Due to its reactivity and the presence of both bromine and iodine atoms, 1-propyne, 3-bromo-1-iodo, can undergo various chemical reactions, such as substitution, addition, and elimination reactions. However, it should be handled with care due to its potential toxicity and reactivity.

77190-22-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77190-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77190-22:
(7*7)+(6*7)+(5*1)+(4*9)+(3*0)+(2*2)+(1*2)=138
138 % 10 = 8
So 77190-22-8 is a valid CAS Registry Number.

1-Iodoacetylenes. Part 2. Formation Constants of their Complexes with Lewis Bases

Laurence, Christian,Queignec-Cabanetos, Michele,Wojtkowiak, Bruno

, p. 1605 - 1610 (2007/10/02)

Formation constants of the complexes of 1-iodoacetylenes (1)-(8) with Lewis bases (9)-(15) have been measured in solution by i.r. spectrophotometry.The stoichiometry of the complexes, the influence of the solvent on the equilibrium position, the existence of linear free energy relationships in the series of iodinated Lewis acids RI, where R=I, Br, Cl, CN, and CCX, and the relation between i.r. frequency shifts and stability constants are discussed.With any electron donor, 1-iodoacetylenes form less stable complexes than those formed by iodine cyanide.With hard bases, iodocyanoacetylene (8) and ethyliodopropiolate (7) give complexes wich are, respectively, more stable than and as stable as those with iodine; however, iodine complexes with soft bases are more stable.This is rationalized, in terms of empirical acidity scales, by the necessity to correlate the thermodynamic and spectroscopic properties of the RI complexes by a double scale equation.
