Mal-PEG2-acid is a PEG (polyethylene glycol) linker that features a maleimide group and a terminal carboxylic acid. This molecule is designed to enhance solubility in aqueous environments due to its hydrophilic PEG spacer. The maleimide group within Mal-PEG2-acid is capable of forming a covalent bond with a thiol group, allowing for the attachment of biomolecules with thiol moieties. Additionally, the terminal carboxylic acid can react with primary amine groups in the presence of specific activators, such as EDC or HATU, to create a stable amide bond.

Used in Diagnostic Industry:
In the diagnostic field, Mal-PEG2-acid is used as a component in the development of imaging agents. The ability to form covalent bonds with biomolecules and drug carriers enables the creation of targeted imaging agents that can be used for various diagnostic applications, such as detecting specific diseases or monitoring the progress of a treatment.
Used in Research and Development:
Mal-PEG2-acid serves as a valuable tool in research and development for the creation of novel bioconjugates. Its unique properties allow for the design and synthesis of new molecules with specific functions, such as targeted drug delivery systems, biosensors, and other bioanalytical tools.
Used in Drug Delivery Systems:
Mal-PEG2-acid is used as a key component in the development of drug delivery systems, particularly for the attachment of therapeutic agents to nanoparticles or other drug carriers. The formation of stable covalent and amide bonds ensures the efficient delivery of the therapeutic agent to the target site, reducing side effects and improving the overall efficacy of the treatment.

Check Digit Verification of cas no

The CAS Registry Mumber 1374666-32-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,6,6 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1374666-32:
(9*1)+(8*3)+(7*7)+(6*4)+(5*6)+(4*6)+(3*6)+(2*3)+(1*2)=186
186 % 10 = 6
So 1374666-32-6 is a valid CAS Registry Number.
