81503-62-0 Usage
General Description
2,4,6-trimethylbenzo[h]quinoline, also known as TMQ, is a polycyclic aromatic hydrocarbon that is commonly used as a stabilizer in rubber products. It is a yellow crystalline powder that is insoluble in water but soluble in organic solvents. TMQ acts as an antioxidant and an antidegradant, helping to prevent the degradation of rubber materials caused by exposure to heat, oxygen, and ozone. It is also used in the production of tires, as well as other rubber and plastic products, to enhance their durability and lifespan. There is limited information available on the potential health and environmental effects of TMQ, and further research is needed to fully understand its impact.
Check Digit Verification of cas no
The CAS Registry Mumber 81503-62-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,0 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81503-62:
(7*8)+(6*1)+(5*5)+(4*0)+(3*3)+(2*6)+(1*2)=110
110 % 10 = 0
So 81503-62-0 is a valid CAS Registry Number.

A facile synthesis of benzo[h]quinolines has been developed via improved Combes reaction. A combination of silica gel, p-toluenesulfonic acid and phosphorus pentoxide was utilized to promote the condensation of 1-naphthylamines with 1,3-diketones under solvent free conditions. In this case, silica gel was used as reaction media, p-toluenesulfonic acid and phosphorus pentoxide were acted as catalyst and dehydrating agent, respectively.
