Description

1,4-Diamino-2-Butyne is a versatile alkyne-containing diamine building block with significant synthetic utility. This compound matters for its bifunctional reactivity, offering both nucleophilic amino groups and an electrophilic alkyne moiety for click chemistry and cross-coupling reactions. It is primarily needed by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A key building block for synthesizing heterocyclic compounds, active pharmaceutical ingredients (APIs), and potential drug candidates.
• Agrochemical Synthesis: Used in the production of novel herbicides, fungicides, and plant growth regulators.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for creating specialty polyamides, polyurethanes, and other polymers with tailored properties.
• Click Chemistry Reagent: The alkyne group enables efficient Huisgen 1,3-dipolar cycloaddition reactions with azides for bioconjugation and material surface modification.
• Ligand Synthesis: Used to prepare chelating ligands for catalysis and metal-organic frameworks (MOFs).
• Corrosion Inhibitor Precursor: A starting material for formulating advanced corrosion inhibitors for industrial applications.

Quality Control

Our 1,4-Diamino-2-Butyne is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
