Tris[p-(dimethylamino)phenyl]methyl chloride, also known as tris(4-dimethylaminophenyl)methyl chloride or TDM, is a chemical compound with the molecular formula C21H24ClN3. It is a white crystalline solid that is soluble in organic solvents and has a melting point of approximately 90°C. TDM is a versatile intermediate in the synthesis of various organic compounds, particularly in the production of dyes, pigments, and pharmaceuticals. It is synthesized by reacting 4-dimethylaminophenol with paraformaldehyde and hydrochloric acid. Due to its reactivity, TDM is often used as a precursor in the preparation of other complex molecules, making it an important building block in the chemical industry.

596-47-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 596-47-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 596-47:
(5*5)+(4*9)+(3*6)+(2*4)+(1*7)=94
94 % 10 = 4
So 596-47-4 is a valid CAS Registry Number.

Orthoamide, LX [1]. N,N,N',N'-Tetraformylhydrazine- a Formylation Agent for Aromatic Compounds of Wide Scope

Kantlehner, Willi,Haug, Erwin,Scherr, Oliver,Stoyanov, Edmont V.,Mezger, Jochen,Ziegler, Georg

, p. 355 - 365 (2007/10/03)

The reagent system formed from N,N,N',N'-tetraformylhydrazine (3) and aluminum chloride allows the formylation of aromatic compounds. The scope of the method is comparable with the Olah formylation and the Gross-Rieche procedure, since benzene and fluorobenzene can be formylated. Two formyl groups are transferred from 3 to the aromatic nuclei when a molar ratio 4:1:4 (aluminum chloride/3/aromatic compound) is chosen.
