Description

Butanoyl Chloride, 4-Amino- is a specialized organic intermediate featuring both an amino group and an acid chloride functionality. This bifunctional nature makes it a valuable building block for the synthesis of more complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought after by research chemists and process development scientists for constructing amide bonds and introducing the 4-aminobutanoyl moiety into target compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a functionalized butyric acid derivative.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the 4-aminobutanoyl structure is integral.
• Peptide Mimetics & Linker Chemistry: Employed in medicinal chemistry for creating peptide analogs and bioconjugation linkers due to its reactive acid chloride group.
• Polymer Modification: Serves as a monomer or grafting agent for introducing amine-reactive sites or pendant amino groups into polymer chains.
• Organic Synthesis Reagent: A versatile reagent for nucleophilic acyl substitution reactions in academic and industrial research laboratories.
• Dye and Pigment Manufacturing: Intermediate in the synthesis of specialized dyes and colorants.
