Chemical biology thrives on the ability to precisely manipulate and study biological systems at the molecular level. This often requires specialized chemical tools that can selectively modify or link biomolecules. 4-Maleimidobenzoic acid (CAS 17057-04-4) is one such indispensable reagent, offering unique functionalities that are highly valued in chemical biology research. As a dedicated supplier of this versatile compound, we provide researchers with the high-quality material necessary to push the boundaries of scientific discovery.

The Maleimide Functionality: Targeting Thiols with Precision

The hallmark of 4-Maleimidobenzoic acid is its maleimide moiety. This functional group is highly reactive towards sulfhydryl (thiol) groups found in cysteine residues of proteins. This selective reactivity allows chemists to specifically attach other molecules to these thiol groups, a process fundamental to many chemical biology techniques. For instance, researchers can use it to label proteins with fluorescent tags for imaging studies, attach affinity matrices for protein purification, or create cross-links to stabilize protein structures and study their conformational changes. When researchers decide to buy 4-Maleimidobenzoic acid, they are investing in a tool that ensures precise and controlled biomolecule modification.

The Carboxylic Acid: A Gateway to Further Functionalization

Complementing the maleimide group is the carboxylic acid function of 4-Maleimidobenzoic acid. This group provides a reactive handle that can be further derivatized. It can be activated for amide bond formation with amines, esterified with alcohols, or used in other conjugation chemistries. This dual reactivity significantly expands the utility of 4-Maleimidobenzoic acid, allowing for the creation of complex molecular architectures and multi-functional probes. This versatility makes it an attractive choice for researchers looking for versatile chemical building blocks.
