An alternative synthesis starts with the ethyl ester of 4-hydroxybenzoic acid, which chlorinates at the positions flanking the phenolic center. Ester hydrolysis followed by decarboxylation affords 2,6-dichlorophenol.
CAS number C 10 H 16 N 2 O 8: Ethylenediaminetetraacetic acid (EDTA) 6381–92–6 C 12 H 22 O 11: sucrose: 57–50–1 C 18 H 29 O 3 S: sodium dodecyl benzenesulfonate: 2155–30–0 C 20 H 25 N 30: Lysergic acid diethylamide (LSD) 50–37–3 C 123 H 193 N 35 O 37: Common serum albumin (macromolecule) 9048–49–1 Ca(AlH 4) 2: calcium ...
3,4-Epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate (ECC) is a cycloaliphatic epoxy resin which is used in many industrial applications. It reacts by cationic polymerization using thermolatent photoinitiators to form crosslinked insoluble thermosets .
Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.
The half-life of this substance in terms of volatilization in the river, lagoon and lake is 2.1 h, 25 h and 18 days, respectively. [20] [21] The amount of methyl chloride in the stratosphere is estimated to be 2 × 10 6 tonnes per year, representing 20–25% of the total amount of chlorine that is emitted to the stratosphere annually.

Cycloastragenol is a triterpenoid isolated from various legume species in the genus Astragalus that is purported to have telomerase activation activity. A preliminary in vitro study on human CD4 and CD8 T cells found that cycloastragenol may moderately increase telomerase activity and inhibit the onset of cellular senescence.
1-(2-Chloro-N-methylbenzimidoyl)cyclopentanol, sometimes misleadingly referred to as hydroxylimine hydrochloride, is a chemical compound which is the final intermediate in the synthesis of ketamine, an anaesthetic drug which is also subject to recreational abuse.
The solubility of another chlorine solvent, carbon tetrachloride, at 0 °C is about 30% (3.11 mol/L). One mole of C 4 Cl 6 can dissolve more chlorine than one mole of CCl 4, but the molecular weight difference between the two solvents is such that per liter of solvent, more chlorine can be dissolved in carbon tetrachloride. Shown below is the ...
