Ethylenediamine has also been used in dermatologic preparations, but has been removed from some because of causing contact dermatitis. [12] When used as a pharmaceutical excipient, after oral administration its bioavailability is about 0.34, due to a substantial first-pass effect. Less than 20% is eliminated by renal excretion. [13]
EDDHA or ethylenediamine-N,N ′-bis(2-hydroxyphenylacetic acid) is a chelating agent. Like EDTA, it binds metal ions as a hexadentate ligand, using two amines, two phenolate centers, and two carboxylates as the six binding sites. The complexes are typically anionic. The ligand itself is a white, water-soluble powder.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
The initial product contains HCl, which is removed by heating. Alternatively, (carbonato)bis(ethylenediamine)cobalt(III) chloride reacts with hydrochloric acid at 10 °C to give the same species. [1] [Co(CO 3)(en) 2]Cl + 2 HCl → trans-[CoCl 2 (en) 2]Cl + CO 2 + H 2 O UV-vis spectra of various stages in the conversion of trans-[CoCl 2 (en) 2 ...
Tris(ethylenediamine)cobalt(III) chloride is an inorganic compound with the formula [Co(en) 3]Cl 3 (where "en" is the abbreviation for ethylenediamine). It is the chloride salt of the coordination complex [Co(en) 3] 3+. This trication was important in the history of coordination chemistry because of its stability and its stereochemistry. Many ...
A sample of ethylenediamine, a simple ethyleneamine. Ethyleneamines are a class of amine compounds containing ethylene (-CH 2 CH 2-) linkages between amine groups. These compounds are generally colorless, low-viscosity liquids with a fishy amine odor. They are primarily used as building block chemicals and in epoxy resin curing agent chemistry. [1]
N-(1-Naphthyl)ethylenediamine is an organic compound. It is commercially available as part of Griess reagents, which find application in quantitative inorganic analysis of nitrates , nitrite and sulfonamide in blood, using the Griess test .
In Italy, the laurea [4] (formerly laurea triennale, meaning "three-year laurea") is the most common type of "undergraduate degree".It is equivalent to a bachelor's degree and its normative time to completion is three years (note that in Italy scuola secondaria superiore or Lyceum [secondary or grammar school], takes five years, so it ends at 19 years of age).
