Description

Crotylamine is a versatile, highly reactive primary amine featuring an unsaturated butenyl chain, making it a valuable building block in advanced organic synthesis. Its dual functionality as both an amine and an alkene provides unique reactivity for constructing complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediates: A key synthon for the production of active pharmaceutical ingredients (APIs), particularly in the synthesis of chiral amines and nitrogen-containing heterocycles.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators, where its unsaturated backbone contributes to biological activity.
• Polymer & Resin Modifiers: Serves as a functional monomer or cross-linking agent to introduce amine functionality into polymers, enhancing adhesion, curing properties, and surface characteristics.
• Corrosion Inhibitors: Employed in the formulation of industrial corrosion inhibitors for metal treatment processes and cooling systems.
• Catalyst & Ligand Preparation: Acts as a precursor for the synthesis of specialized ligands used in homogeneous catalysis and organometallic chemistry.
• Fine Chemical Production: Integral in the multi-step synthesis of dyes, pigments, and other high-value specialty chemicals.

Quality Control

Our Crotylamine is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, isomer content, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, and we support our clients' regulatory needs for pharmaceutical and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and strong alkaline nature, store in a cool, well-ventilated place, away from heat sources and incompatible materials such as strong acids and oxidizers. Recommended storage temperature is 2-8°C to maximize stability. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
