2-Fluoro-5-bromobenzyl bromide CAS 99725-12-9
Introduction
Toxin peptides are a class of toxic peptide molecules, usually produced by bacteria, plants, or animals. The properties of toxin peptides depend on their structure and source, and some are neurotoxic, cytotoxic, or otherwise biological. CALCISEPTINE IS A TOXIN PEPTIDE WITH CAS NUMBER 178805-91-9, AND ITS SPECIFIC PROPERTIES REQUIRE FURTHER INVESTIGATION.
The preparation of toxin peptides usually needs to be extracted from living organisms or obtained by synthetic methods, and the preparation process can be complex and requires professional technical support.
Toxin peptides are potentially toxic, and the dosage and concentration need to be strictly controlled when used to avoid harm to the human body or the environment. When operating in the laboratory, you need to wear personal protective equipment and follow the relevant safety operating procedures. For the research and application of toxin peptides, relevant regulations and safety standards should be followed to ensure the safety of people and the environment.
Application
2-Fluoro-5-bromobenzyl bromide is a high-purity, bifunctional alkylating agent designed for precision organic synthesis and pharmaceutical research. Its dual halogen handles—a reactive benzylic bromide and an aromatic bromo/fluoro substitution pattern—enable orthogonal functionalization via nucleophilic substitution (SN2) and transition-metal-catalyzed cross-couplings (e.g., Suzuki-Miyaura, Buchwald-Hartwig, Sonogashira). As a key pharmaceutical intermediate and advanced building block, it is particularly valued for the synthesis of bioactive heterocycles, including the alkylation of β-amino esters to construct benzazepine and benzodiazepine scaffolds for CNS drug discovery (e.g., anti-anxiety and anticonvulsant agents). It also serves as a versatile linker for targeted covalent inhibitors (e.g., proteolysis-targeting chimeras) and for introducing halogenated aryl motifs into drug-like molecules for oncology and antibacterial research. The regiospecific fluorine substituent enhances metabolic stability and binding affinity, making it an indispensable custom chemical synthesis reagent for hit-to-lead optimization and GMP manufacturing. Xinchem provides reliable custom synthesis, custom chemical synthesis, and contract manufacturing of this versatile benzyl halide with flexible scaling from R&D to commercial tons.
