General Description
DIETHYL ETHYLCHLOROMALONATE is an organic compound commonly used as a reagent in organic synthesis. It is a clear, colorless liquid that is soluble in organic solvents such as ethanol and acetone. The compound is derived from ethyl chloromalonate and is typically used in the production of pharmaceuticals and agrochemicals. Its chemical structure contains a malonate ester group, which makes it useful for esterification and condensation reactions. It is also used as a building block in the synthesis of complex organic molecules and has applications in the field of medicinal chemistry. Additionally, DIETHYL ETHYLCHLOROMALONATE is a potential irritant and should be handled with care in a laboratory setting.
Check Digit Verification of cas no
The CAS Registry Mumber 29263-83-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,2,6 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 29263-83:
(7*2)+(6*9)+(5*2)+(4*6)+(3*3)+(2*8)+(1*3)=130
130 % 10 = 0
So 29263-83-0 is a valid CAS Registry Number.

Phase transfer catalyzed halogenation of carbon acids
-
, (2008/06/13)
A process is disclosed for chlorinating, brominating and/or iodinating an organic substrate containing both a single acidic hydrogen atom and at least one electron withdrawing group attached to the same carbon atom. The process replaces the single acidic hydrogen with chlorine, bromine and/or iodine and involves reacting the substrate in solution with a halogenating agent (e.g., a perhalomethane wherein the halogen substituents are I, Br and/or Cl, a trihaloacetic acid ester wherein the halogen substituents are Br and/or Cl, or a perfluoroalkyl halide wherein the halide is I, Br and/or Cl) in the presence of (i) a phase transfer catalyst of the formula R1 R2 R3 R4 LJ where L is selected from the group consisting of phosphorus and nitrogen, where J is an inorganic anion other than fluoride, and where R1, R2, R3 and R4 are independently chosen from the froup consisting of hydrocarbyl radicals containing from 1 to about 20 carbon atoms and (ii) a mild inorganic base which is insoluble in the reaction medium.
