97-90-5 Usage
Description
Different sources of media describe the Description of 97-90-5 differently. You can refer to the following data:
1. It is mainly applied in the field of organic synthesis, such as a crosslinking agent for fabricating resin, resin processing, fabricating adhesives and coatings, rubber resin modifier, anaerobic adhesive, and plastic paste. Specifically, this chemical can be used as the raw material to prepare a copolymer that has been demonstrated to act as a biocompatible interface between glucose biosensors and tissue in the rat.1 Moreover, this compound may be involved in the preparation of poly(2-vinyl-4,4-dimethylazlactone-co-acrylamide-co-ethylene dimethacrylate) for designing the porous support for high throughput reactors.2 In addition, the bulk polymerization of this chemical and glycidyl methacrylate results in the formation of porous monolith as a stationary phase in dye-affinity chromatography.3
2. The crosslinking agent of acrylic resins, ethyleneglycol
dimethacrylate (EGDMA), is employed to optimize the
dilution of high-viscosity monomers and to link
together the macromolecules costituting the polymer.
It caused contact dermatitis in dental technicians and
dental assistants. A case was also reported in a car
rear-view mirror manufacturer.

Definition
ChEBI: The enoate ester that is the 1,2-bis(methacryloyl) derivative of ethylene glycol.
General Description
Ethylene glycol dimethylacrylate (EGDMA) is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 97-90-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97-90:
(4*9)+(3*7)+(2*9)+(1*0)=75
75 % 10 = 5
So 97-90-5 is a valid CAS Registry Number.
