Dioctyl-diphenyl-germane, also known as bis(2-ethylhexyl)diphenylgermane, is an organogermanium compound with the chemical formula C28H44Ge. It is a colorless, viscous liquid that is insoluble in water but soluble in organic solvents. Dioctyl-diphenyl-germane is primarily used as a stabilizer for polyvinyl chloride (PVC) and other polymers, preventing the degradation of these materials under heat and light exposure. Dioctyl-diphenyl-germane functions by interrupting the autocatalytic dehydrochlorination process in PVC, thereby extending the material's lifespan and maintaining its physical properties. Due to its effectiveness and low toxicity, it is widely used in the plastics industry, particularly in the production of flexible PVC products such as films, cables, and hoses.

Check Digit Verification of cas no

The CAS Registry Mumber 4237-11-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4237-11:
(6*4)+(5*2)+(4*3)+(3*7)+(2*1)+(1*1)=70
70 % 10 = 0
So 4237-11-0 is a valid CAS Registry Number.

Preparation and Some Reactions of Diarylgermylenedialkali Metals

Mochida, Kunio,Matsushige, Naoki,Hamashima, Mari

, p. 1443 - 1447 (2007/10/02)

The reactions of diarylgermanes with alkali metals in HMPA/THF or THF were found to give the corresponding diarylgermylenedialkali metals in high yields.Diphenylgermylenedipotassium reacted with aryl halides or carbonyl compounds to give reduction products predominantly.With alkyl halides, diphenylgermylenedipotassium gave mainly substitution products.
