Product Packaging
Maintaining strict purity levels for precision applications—such as semiconductor and colloidal synthesis—requires rigorous quality control. Every export batch of CAS 112-90-3 undergoes thorough self-inspection in our in-house analytical testing center before a formal Certificate of Analysis (COA) is issued:
Gas Chromatography (GC-FID) Analysis: Verifies carbon chain length distribution (C18 content) and ensures minimal presence of saturated amine impurities (e.g., stearylamine or octadecylamine).
Potentiometric Amine Titration: Quantifies total amine value to confirm high primary amine purity while limiting secondary and tertiary amine sub-products.
Karl Fischer Volumetric Moisture Determination: Ensures water content remains strictly below 0.5%, preventing unwanted phase separation or reaction quenching during moisture-sensitive organometallic reactions.
Physical Refractive Index & Density Profiling: Confirms rapid phase uniformity and absence of particulate contaminants.
Due to its dual affinity—a hydrophilic amine group paired with a hydrophobic unsaturated tail—Oleylamine is widely utilized across multiple advanced sectors:
Nanotechnology & Quantum Dot Synthesis: Functions as an effective capping ligand and structure-directing agent during the synthesis of metal nanoparticles (gold, silver, platinum), semiconductor quantum dots (CdSe, Perovskites), and magnetic iron oxide (Fe₃O₄) nanocrystals. It controls crystal growth rates and prevents nanoparticle aggregation in organic solvents.
Corrosion Inhibition & Oilfield Chemicals: Forms a durable, hydrophobic protective film on steel surfaces, mitigating acidic corrosion in oilfield pipelines and industrial water treatment systems.
Specialty Surfactants & Intermediate Synthesis: Serves as a primary building block for cationic surfactants, amphoteric betaines, amine oxides, and textile softening agents.
Lubricant & Fuel Additives: Improves extreme-pressure lubrication performance, boundary friction reduction, and anti-wear properties in automotive and industrial lubricating oils.
FAQ
A: Oleylamine plays a dual role as both a high-boiling solvent/reducing agent and a surface-coordinating ligand. Its lone pair of electrons on the nitrogen atom binds to metallic or semiconductor crystal surfaces during nucleation, regulating particle growth, passivating surface defects, and granting excellent dispersibility in non-polar organic solvents like hexane or toluene.
A: Yes. We provide pre-shipment sample testing along with complete COA, MSDS/SDS, and analytical spectrum data (GC/FTIR) to ensure full technical alignment prior to contract execution.
