1528-44-5 Usage

General Description

1,3-Benzenedicarboxylic acid, bis(1-Methylethyl) ester, also known as dimethyl terephthalate, is a chemical compound commonly used as a monomer in the production of polyethylene terephthalate (PET) and other polymers. It is a clear, colorless liquid with a faintly fruity odor. This chemical is considered safe for use in consumer products and has a wide range of applications, including in the production of food and beverage containers, polyester film, textiles, and engineering resins. It is important to handle this compound with care, as it may cause irritation to the eyes, skin, and respiratory system upon exposure.

Check Digit Verification of cas no

The CAS Registry Mumber 1528-44-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,2 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1528-44:
(6*1)+(5*5)+(4*2)+(3*8)+(2*4)+(1*4)=75
75 % 10 = 5
So 1528-44-5 is a valid CAS Registry Number.

Efficient synthesis of esters through oxone-catalyzed dehydrogenation of carboxylic acids and alcohols

Hou, Fei,Wang, Xi-Cun,Quan, Zheng-Jun

supporting information, p. 9472 - 9476 (2019/01/03)

Since esters are important organic synthesis intermediates, an environmentally friendly oxone catalyzed-esterification of carboxylic acids with alcohols has been developed. A series of carboxylic acid esters are obtained in high yield. This strategy requires mild reaction conditions, providing an attractive alternative for the construction of valuable carbonyl esters. Electron-rich and electron-deficient groups are compatible with the standard conditions and a variety of substrates are demonstrated. Moreover, the reaction could easily be adapted to typical prodrugs, drugs and gram-scale synthesis.
