1,3,3-tris(trimethylsilyl)propyne is an organosilicon compound with the chemical formula (CH3)3Si-C≡C-Si(CH3)3. It is a colorless, volatile liquid that is highly sensitive to air and moisture. 1,3,3-tris(trimethylsilyl)propyne is characterized by its unique structure, featuring a propyne backbone with three trimethylsilyl groups attached to the terminal carbon atoms. The presence of these bulky trimethylsilyl groups results in a significant steric hindrance, which affects the compound's reactivity and stability. 1,3,3-tris(trimethylsilyl)propyne is primarily used as a precursor in the synthesis of various organosilicon compounds and has potential applications in the fields of materials science and chemical research. Due to its sensitivity, it must be handled with care and stored under an inert atmosphere to prevent decomposition.

3401-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3401-29-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,0 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3401-29:
(6*3)+(5*4)+(4*0)+(3*1)+(2*2)+(1*9)=54
54 % 10 = 4
So 3401-29-4 is a valid CAS Registry Number.

UNE VOIE D'ACCES RAPIDE ET PRATIQUE AU TETRAKIS(TRIMETHYLSILYL)-ALLENE ET AU BIS(TRIMETHYLSILYL)-1,3 PROPYNE

Bennetau, Bernard,Youhouvoulou N'Gabe, Denis,Dunogues, Jacques

, p. 3813 - 3816 (2007/10/02)

Complete silylation of hexachlorobenzene using the Me3SiCl/Li/THF reagent at 0oC quantitatively affords tetrakis(trimethylsilyl)allene.This last upon a double protodesilylation with F3CCOOH at 0o, leads to the quantitative formation of 1,3-bis(trimethylsilyl)propyne via the 1,3,3-tris(trimethylsilyl)propyne.
