503603-67-6 Usage
Chemical structure
1,4-Benzenedicarboxylic acid, 2,5-bis[(4-methylphenyl)methyl]-
Physical state
Colorless, odorless liquid
Properties
Highly resistant to heat and chemicals
Applications
Widely used in the production of plastics, particularly in the manufacture of polyvinyl chloride (PVC) products
Usage in industry
Commonly used in the production of food packaging materials, medical devices, toys, and various other consumer products
Safety
Considered a safer alternative to phthalate plasticizers, as it does not contain the same harmful chemicals

Low to moderate viscosity as a liquid
Compatibility
Compatible with PVC and other polymers for use as a plasticizer
Environmental impact
Generally considered to have a lower environmental impact compared to other phthalate plasticizers
Regulatory status
DOTP is not listed as a high priority for regulation under the European Union's REACH regulation, indicating a lower concern for human health and the environment
Manufacturing process
Produced through a chemical reaction between terephthalic acid and octanol, followed by esterification and purification steps
Storage
Should be stored in a cool, dry, and well-ventilated area, away from heat and open flames
Handling precautions
Use appropriate personal protective equipment (PPE) when handling DOTP, such as gloves, goggles, and a respirator if necessary.
Check Digit Verification of cas no
The CAS Registry Mumber 503603-67-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,6,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 503603-67:
(8*5)+(7*0)+(6*3)+(5*6)+(4*0)+(3*3)+(2*6)+(1*7)=116
116 % 10 = 6
So 503603-67-6 is a valid CAS Registry Number.
