Diethyl malonate, also known as DEM, is the diethyl ester of malonic acid. It occurs naturally in grapes and strawberries as a colourless liquid with an apple-like odour, and is used in perfumes. It is also used to synthesize other compounds such as barbiturates, artificial flavourings, vitamin B1, and vitamin B6.
The Reissert reaction is a series of chemical reactions that transforms quinoline to quinaldic acid. Quinolines will react with acid chlorides and potassium cyanide to give 1-acyl-2-cyano-1,2-dihydroquinolines, also known as Reissert compounds. Hydrolysis gives the desired quinaldic acid.
Naphthol Red is an organic pigment extensively used in automotive coatings and painting.
Etonitazene, also known as EA-4941 or CS-4640, is a benzimidazole opioid, first reported in 1957, that has been shown to have approximately 1,000 to 1,500 times the potency of morphine in animals.
Baby shampoo /ˈbeɪbi/ /ʃæmˈpuː/ is a hair care product that is used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminant particles that gradually build up in hair; specially formulated for use on infants and young children by means of substituting chemicals which are purportedly less irritating to the eyes than those commonly found in regular shampoo.
The CALS Table Model is a standard for representing tables in SGML/XML. It was developed as part of the CALS DOD initiative.
MME (2,4-dimethoxy-5-ethoxyamphetamine) is a lesser-known psychedelic drug. It is a dimethoxy-ethoxy analog of TMA-2. MME was first synthesized by Alexander Shulgin from ethylvanillin. In his book PiHKAL, the minimum dosage is listed as 40 mg and above, and the duration listed as 6–10 hours. Shulgin gives MME a ++ on the Shulgin Rating Scale.
The Diels–Reese Reaction is a reaction between hydrazobenzene and dimethyl acetylenedicarboxylate first reported in 1934 by Otto Diels and Johannes Reese. Later work by others extended the reaction scope to include substituted hydrazobenzenes. The exact mechanism is not known. By changing the acidic or basic nature of the solvent, the reaction gives different products. With acetic acid as solvent (acidic), the reaction gives an diphenylpyrazolone. With xylene as solvent (neutral), the reaction gives an indole. With pyridine as solvent (basic), the reaction gives a carbomethoxyquinoline which can be degraded to a dihydroquinoline.
In enzymology, a 5,6-dihydroxy-3-methyl-2-oxo-1,2,5,6-tetrahydroquinoline dehydrogenase (EC 1.3.1.65) is an enzyme that catalyzes the chemical reaction
In enzymology, a quinoline-4-carboxylate 2-oxidoreductase (EC 1.3.99.19) is an enzyme that catalyzes the chemical reaction
The Gould–Jacobs reaction is an organic synthesis for the preparation of quinolines and 4‐hydroxyquinoline derivatives. The Gould-Jacobs reaction is a series of reactions. The series of reactions begins with the condensation/substitution of an aniline with alkoxy methylenemalonic ester or acyl malonic ester, producing anilidomethylenemalonic ester. Then through a 6 electron cyclization process, 4-hydroxy-3-carboalkoxyquinoline is formed, which exist mostly in the 4-oxo form. Saponification results in the formation of an acid. This step is followed by decarboxylation to give 4-hydroxyquinoline. The Gould-Jacobs reaction is effective for anilines with electron‐donating groups at the meta‐position.
Pirimiphos-methyl, marketed as Actellic, and Sybol is a phosphorothioate used as an insecticide. It was originally developed by Imperial Chemical Industries Ltd., now Syngenta, at their Jealott's Hill site and first marketed in 1977, ten years after its discovery.
Ethylvanillin is the organic compound with the formula (C2H5O)(HO)C6H3CHO. This colorless solid consists of a benzene ring with hydroxyl, ethoxy, and formyl groups on the 4, 3, and 1 positions, respectively. It is a homologue of vanillin, differing on the 3 position.
1,3-Indandione (sometimes simply indanedione) is an organic compound with the molecular formula C6H4(CO)2CH2. It is a β-diketone on an indane framework. It is a colorless or white solid although samples can appear yellowish or even green. It is a widely used building block
The molecular formula C14H17NO3 (molar mass : 247.28 g/mol) may refer to :
2CD-5EtO is a homologue of the psychedelic phenethylamine 2C-D, where the 5-methoxy group of 2C-D has been lengthened to an ethoxy group. 2CD-5EtO is a representative example of the so-called "tweetio" compounds discovered by Alexander Shulgin and briefly mentioned in his book PiHKAL. They are homologues of the 2C family of drugs, where either one or both of the methoxy groups at the 2,5-positions of the aromatic ring have been replaced by ethoxy. The term tweetio was derived phonetically from the sound of the "2-ETO" derivatives.
Floctafenine is a nonsteroidal anti-inflammatory drug (NSAID).
In organic chemistry, the Cornforth rearrangement is a rearrangement reaction of a 4-acyloxazole in which the group attached to an acyl on position 4 and the substituent on position 5 of an oxazole ring exchange places. It was first reported in 1949, and is named for John Cornforth. The reaction is used in the synthesis of amino acids, where the corresponding oxazoles occur as intermediates.
2-Ethoxycarbonyl-1-methylvinyl cyclohexyl methylphosphonate is an extremely toxic organophosphate nerve agent. It is the cyclohexyl methylphosphonate ester of ethyl acetoacetate. The compound has two isomers, the cis isomer and trans isomer, with the trans isomer being more toxic.
