N,N'-bis(p-chlorophenyl)ethylenediamine, also known as 4,4'-dichloro-diphenyl-ethylenediamine or simply "DDPA," is an organic compound with the chemical formula C14H12Cl2N2. It is a white crystalline solid that is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals and agrochemicals, including the production of fungicides and herbicides. DDPA is known for its ability to chelate metal ions, which makes it useful in stabilizing metal catalysts and in the preparation of metal complexes. It is also used in the rubber industry as an accelerator and in the manufacturing of dyes. Due to its chemical reactivity and potential health risks, it is important to handle DDPA with care, following proper safety protocols.

4672-69-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4672-69-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4672-69:
(6*4)+(5*6)+(4*7)+(3*2)+(2*6)+(1*9)=109
109 % 10 = 9
So 4672-69-9 is a valid CAS Registry Number.

Thiadiazolidine 1-oxide systems for phosphine-free palladium-mediated catalysis

Buckley, Benjamin R.,Neary, Stephen P.

experimental part, p. 7988 - 7994 (2010/10/21)

We herein report several highly active catalyst systems with thiadiazolidine 1-oxides as ligands for palladium in the Mizoroki-Heck reaction. Excellent yields of stilbenes derived from aryl iodides and bromides have been achieved using as little as 0.00002 mol % catalyst. The ligand/palladium system can be stored as a stock solution open to air at room temperature with no observable loss of activity for a period of several months.
