3342-67-4 Usage
General Description
Tripentyltin chloride, also known as TPTC, is an organotin compound with the chemical formula (C5H9)3SnCl. It is a colorless liquid that is highly soluble in organic solvents. TPTC is commonly used as a catalyst in organic synthesis, particularly in the production of polyurethane foams and coatings. It is also utilized as a stabilizer in the production of PVC and as a crosslinking agent in the manufacture of silicone rubber. Due to its toxic and harmful effects on the environment and human health, the use and production of TPTC have become regulated in many countries.
Check Digit Verification of cas no
The CAS Registry Mumber 3342-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3342-67:
(6*3)+(5*3)+(4*4)+(3*2)+(2*6)+(1*7)=74
74 % 10 = 4
So 3342-67-4 is a valid CAS Registry Number.

RECYCLING OF ORGANOTIN COMPOUNDS
-
, (2013/12/03)
A method for the synthesis of a first organic molecule, said method comprising the steps of: a) Reacting a first reactant with an organotin reactant having at least one optionally substituted organic group having from 5 to 20 carbon atoms selected from alkyl, alkenyl, alkynyl, alkoxyalkyl, alkoxy, alkylthioalkyl, carboxylates and alkylaminoalkyl groups, thereby forming a mixture of a product and a tin-containing by-product, and b) Removing most of the tin-containing by-product from said mixture in such a way as to provide a purified product comprising less than 1000 ppm of remaining tin-containing by- product, wherein said step of removing most of said tin-containing by-product is either an extraction between a first liquid and a second liquid, said second liquid being more polar than said first liquid and at least partly immiscible therewith or is a reversed phase chromatography.
