42967-55-5 Usage
General Description
Terephthalic acid monomethyl ester potassium salt is a chemical compound commonly used as a plasticizer in the manufacturing of polyethylene terephthalate (PET) resin. It is derived from terephthalic acid, a key ingredient in the production of polyester fibers and resins, and is commonly found in various consumer products such as clothing, beverage containers, and packaging materials. As a potassium salt, it is often added to PET resin to improve its flexibility and durability, making it suitable for a wide range of applications. However, there are concerns about the potential health and environmental impacts of this chemical, and its usage is closely regulated by government agencies to ensure safe handling and disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 42967-55-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42967-55:
(7*4)+(6*2)+(5*9)+(4*6)+(3*7)+(2*5)+(1*5)=145
145 % 10 = 5
So 42967-55-5 is a valid CAS Registry Number.

Unsymmetrical dicarboxylic esters as bleach precursors
-
, (2008/06/13)
A bleach precursor compound, its peroxygen derivative, and detergent compositions containing these materials are disclosed herein. The bleach precursors structurally comprise a pair of different diesters, one ester containing an electrically-charged functional group. Perhydrolysis of the precursor in the presence of hydrogen peroxide and a basic aqueous media generates a peroxycarboxylic acid.
