This can be worked out from the specific activity expressed in molar terms, where the specific activity of 125I at 100% isotopic abundance is approximately 1.8 mCi/nmol. For example, assume that 20 μg of a peptide hormone of molecular weight 20,000, such as hPL, hGH, or prolactin, is...

The iodine value is the mass of iodine in grams that is consumed by 100 grams of a chemical substance typically fats or oils. Iodine numbers are often used to determine the amount of unsaturation in fatty acids. This unsaturation is in the form of double bonds, which react with iodine comp...

Mono- and difunctional perfluorinated alkyl compounds, namely C6F13I, C4F9I, and C4F8I2, were used as chain transfer agents (CTAs). The impact of the structure and concentration of these CTAs on molar mass and particle size distributions was investigated. The difunctional CTA is associated with...

Some chemicals listed in this database or not pure chemical compounds, rather they are mixtures/solutions of chemicals. It is not uncommon for wide range of molar ratios of a mixture to be lumped together as "synonyms" of the same "chemical". In some instances chemicals that are very simila...
