CAS 142439-92-7: biotin disulfide N-hydroxysuccinimide*ester

Description: Biotin disulfide N-hydroxysuccinimide ester, with the CAS number 142439-92-7, is a chemical compound that serves as a bioconjugation reagent, particularly in the field of biochemistry and molecular biology. This compound features a biotin moiety, which is a vitamin that plays a crucial role in cellular metabolism and is widely used in various biochemical applications due to its strong affinity for avidin or streptavidin. The presence of the disulfide bond allows for the formation of stable conjugates, while the N-hydroxysuccinimide (NHS) ester functionality facilitates the reaction with amine-containing molecules, enabling the attachment of biotin to proteins, peptides, or other biomolecules. This property is particularly useful in labeling, purification, and detection applications. The compound is typically characterized by its ability to form stable conjugates under mild conditions, making it a valuable tool in the development of assays, drug delivery systems, and in the study of protein interactions. Its reactivity and specificity make it an important reagent in the field of bioorthogonal chemistry.
