PRL-8-53 is a nootropic substituted phenethylamine that has been shown to act as a hypermnesic drug in humans; it was first synthesized by medical chemistry professor Nikolaus Hansl at Creighton University in the 1970s as part of his work on amino ethyl meta benzoic acid esters.
Ethyl benzoate, C 9 H 10 O 2, is an ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents.
Intrahepatic cholestasis of pregnancy (ICP), also known as obstetric cholestasis, cholestasis of pregnancy, jaundice of pregnancy, and prurigo gravidarum, [1] is a medical condition in which cholestasis occurs during pregnancy. [2] It typically presents with itching and can lead to complications for both mother and fetus. [2]
[9] [10] Overdose of only a small number of capsules can be fatal. [10] Chewing or sucking on the capsule, releasing the drug into the mouth, can also lead to laryngospasm, bronchospasm, and circulatory collapse. [7] It is unclear if use in pregnancy or breastfeeding is safe. [11] Benzonatate is a local anesthetic and voltage-gated sodium ...
Methyl isocyanate (MIC) is an organic compound with the molecular formula CH 3 NCO. Synonyms are isocyanatomethane and methyl carbylamine.Methyl isocyanate is an intermediate chemical in the production of carbamate pesticides and Haffmann Bromamide Degradation (such as carbaryl, carbofuran, methomyl, and aldicarb).
The N=C and C=S distances are 117 and 158 pm. [2] By contrast, in methyl thiocyanate, N≡C and C−S distances are 116 and 176 pm. . Typical bond angles for C−N=C in aryl isothiocyanates are near 165°.
Diethylamino hydroxybenzoyl hexyl benzoate is an organic compound used in sunscreens to absorb UVA radiation. It is marketed as Parsol DHHB by DSM and as Uvinul A Plus by BASF. DHHB has an absorption maximum of 354 nm. [1] [2] DHHB has excellent photostability and compatibility with other UV absorbers and other cosmetic ingredients. [3]
