25249-16-5 Usage

Description

Poly(2-hydroxyethyl methacrylate), also known as pHEMA, is a versatile polymer with both hydrophilic and hydrophobic properties. It is composed of repeating 2-hydroxyethyl 2-methylpropanoate units and is characterized by non-covalent interactions of hydrogen-bonds among the polymer chains and the hydrated water molecules. The presence of polar hydroxyl and carboxyl groups on each repeat unit makes this polymer compatible with water, while the hydrophobic α-methyl groups of the backbone provide hydrolytic stability and enhance the mechanical strength of the polymer matrix.

Uses

Used in Biomedical Applications:
pHEMA is used as a nonadhesive substrate in the preparation of single cell suspensions to implant into mice cornea for corneal micropocket assays. It is also used to coat well plates for sphere assays using adipose-derived mesenchymal stem cells.
Used in Tissue Engineering:
pHEMA scaffolds are used in tissue engineering, where they can be utilized in hydrogels for biomedical applications and as sorbents for metal ions.
Used in Ophthalmology:
pHEMA has been used in the development of soft contact lenses, providing a comfortable and effective alternative to traditional hard lenses.
Used in Drug Delivery Systems:
pHEMA is employed in drug delivery systems, where it can be used to control the release of medications and improve their efficacy.
Used in Medical Devices:
pHEMA has been utilized in the production of kidney dialysis membranes, offering improved biocompatibility and performance.
Used in Controlled Drug Delivery:
Nanoparticles of pHEMA may be employed as a carrier for controlled delivery of anticancer and antitumor drugs, enhancing the therapeutic outcomes and reducing side effects.
Used in Different Industries:
In the biomedical industry, pHEMA is used as a versatile material for various applications, including tissue engineering, drug delivery systems, and medical devices.
In the ophthalmology industry, pHEMA is used in the development of soft contact lenses, providing a comfortable and effective alternative to traditional hard lenses.

Biochem/physiol Actions

Check Digit Verification of cas no

The CAS Registry Mumber 25249-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,4 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25249-16:
(7*2)+(6*5)+(5*2)+(4*4)+(3*9)+(2*1)+(1*6)=105
105 % 10 = 5
So 25249-16-5 is a valid CAS Registry Number.

BIOGUM AND BOTANICAL GUM HYDROGEL BIOINKS FOR THE PHYSIOLOGICAL 3D BIOPRINTING OF TISSUE CONSTRUCTS FOR IN VITRO CULTURE AND TRANSPLANTATION

-

, (2021/01/20)

Bioink compositions comprising a biomaterial (mammalian, plant based, synthetically derived, or microbially derived) such as a hydrogel and a microbial-, fungal-, or plant-produced polysaccharide, with or without cells, for use in the 3D bioprinting of human tissues and scaffolds are described. The bioink compositions have excellent printability and improved cell function, viability and engraftment. Furthermore, the bioink compositions can be supplemented through the additional of auxiliary proteins and other molecules such as growth factors including extracellular matrix components, Laminins, super affinity growth factors and morphogens. The bioink compositions can be used under physiological conditions related to 3D bioprinting parameters which are cytocompatible (e.g. temperature, printing pressure, nozzle size, bioink gelation process). The combination of a biogum-based biomaterial together with mammalian, plant, microbial or synthetically derived hydrogels exhibited improvement in printability, cell function and viability compared to tissues printed with bioink not containing biogums.

METHOD FOR PREPARING HYDROXYETHYL (METH) ACRYLATE

-

Paragraph 0033; 0034, (2017/07/14)

Hydroxyethyl (methyl)acrylate is prepared by a process of a combination of a three-stage tubular reactor and a tower reactor, wherein, firstly, a catalyst, a polymerization inhibitor and (methyl) acrylic acid are mixed until the solids are dissolved, then mixed with a part of ethylene oxide and thereafter enter into a first tubular reactor for a reaction, a reaction liquid flowing out from the first tubular reactor is mixed with a certain amount of ethylene oxide and enters into a second tubular reactor for a reaction, a reaction liquid flowing out from the second tubular reactor is then mixed with a certain amount of ethylene oxide and thereafter enters into a third tubular reactor, and a reaction liquid flowing out from the third tubular reactor is then passed through a stage of an adiabatic tower reactor and aged such that a product liquid is obtained from extraction.
