Properties Chemical formula. C 3 H 2 F 4: ... 1,3,3,3-Tetrafluoropropene is a hydrofluoroolefin which has two isomers: cis-1,3,3,3-tetrafluoropropene.
trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze(E)) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a , as a blowing agent for foam and aerosol applications, and in air horns and gas dusters . [ 3 ]
The descriptors cis (Latin, on this side of) [2] and trans (Latin, over, beyond) [3] are used in various contexts for the description of chemical configurations: [4] [5] In organic structural chemistry , the configuration of a double bond can be described with cis and trans , in case it has a simple substitution pattern with only two residues.
1,3-Dichloropropene, sold under diverse trade names, is an organochlorine compound with the formula C 3 H 4 Cl 2. It is a colorless liquid with a sweet smell. It is a colorless liquid with a sweet smell.
Palmitoleic acid has 16 carbons, is found in cod liver oil, sardine oil, and herring oil, and is a cis-9-monounsaturated fatty acid.C 15 H 29 CO 2 H, IUPAC organization name (Z)-hexadec-9-enoic acid, n-7, numerical representation of 16:1, molecular weight 254.41, melting point 5 °C, specific gravity 0.894.
One attractive feature of the Peterson olefination is that it can be used to prepare either cis- or trans-alkenes from the same β-hydroxysilane. Treatment of the β-hydroxysilane with acid will yield one alkene, while treatment of the same β-hydroxysilane with base will yield the alkene of opposite stereochemistry.
In chemistry, hexahydro-1,3,5-triazine is a class of heterocyclic compounds with the formula (CH 2 NR) 3. Known as aldehyde ammonias, these compounds characteristically crystallize with water . They are reduced derivatives of 1,3,5- triazine , which have the formula (CHN) 3 , a family of aromatic heterocycles.
The 3 substrates of this enzyme are cis-1,2-dihydroxy-4-methylcyclohexa-3,5-diene-1-carboxylate, NAD +, and NADP +, whereas its 4 products are 4-methylcatechol, NADH, NADPH, and CO 2. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor.
