Instruments on the " Philae " lander found at least sixteen organic compounds at the comet's surface, four of which ( acetamide, acetone, methyl isocyanate and propionaldehyde ) have been detected for the first time on a comet.

They are sorted by the partition coefficient, smallest to largest ( acetamide being hydrophilic, and 2, 2', 4, 4', 5-pentachlorobiphenyl lipophilic ), and are presented with the temperature at which they were measured ( which impacts the values ).

Results from the Philae " spacecraft, that landed on comet 67P / Churyumov-Gerasimenko in November 2014, detected at least 16 organic compounds, of which four ( including acetamide, acetone, methyl isocyanate and propionaldehyde ) were detected for the first time on a comet.

Hashimoto H, Satoh N, and Nakashima M . Effects of SUN-1165, N-( 2, 6-dimethylphenyl )-8-pyrrolizidine acetamide hydrochloride hemihydrate, a new class I antiarrhythmic drug, on ventricular arrhythmias, intraventricular conduction, and the refractory period in canine myocardial infarction.

In July 2015, scientists reported that upon the first touchdown of the " Philae " lander on comet 67 / P surface, measurements by the COSAC and Ptolemy instruments revealed sixteen organic compounds, four of which were seen for the first time on a comet, including acetamide, acetone, methyl isocyanate and propionaldehyde.
26.
The kinetic studies show that the second-order rate constant for hydroxide-ion catalyzed hydrolysis of acetonitrile to acetamide is 1.6 ?10 " 6, which is slower than the hydrolysis of the amide to the carboxylate ( 7.4 ?10 " 5 M " 1 s " 1 ).

On 30 July 2015, scientists reported that upon the first touchdown of the " Philae " lander on comet 67 / P surface, measurements by the COSAC and Ptolemy instruments revealed sixteen organic compounds, four of which were seen for the first time on a comet, including acetamide, acetone, methyl isocyanate and propionaldehyde.

The measurement of brain uptake of acetamide, antipyrine, benzyl alcohol, butanol, caffeine, cytosine, phenytoin, ethanol, ethylene glycol, heroin, mannitol, methanol, phenobarbital, propylene glycol, thiourea, and urea in ether-anesthetized newborns vs . adult rabbits shows that newborn rabbit and adult rabbit brain endothelia are functionally similar with respect to lipid-mediated permeability.
