Product Name	Dodecanedioic Acid (DDDA) (1,10-Decanedicarboxylic Acid / C12 Dibasic Acid)
CAS NO.	693-23-2
Formula & Weight	HOOC(CH₂)₁₀COOH (C12H22O4) \| MW: 230.30
Technical Specifications	Appearance: White crystalline powder or flake Assay (GC): ≥ 99.0% Melting Point: 127°C - 131°C Water Content: ≤ 0.3% Ash: ≤ 0.1% Solubility: Soluble in hot alcohol; insoluble in water (but salts are soluble).
Industrial Applications	A versatile C12 dicarboxylic acid chain for high-performance materials: High-Performance Polyamides (Nylon): The primary monomer for Nylon 612, Nylon 1212, and Nylon 1012. These nylons offer superior flexibility, low moisture absorption, and chemical resistance for automotive fuel lines and cable ties. Corrosion Inhibitors: Reacts with amines to form salts that act as effective rust inhibitors in Metalworking Fluids (MWF), engine coolants, and water treatment systems. Powder Coatings: Used as a cross-linking curing agent for acrylic and polyester resins, providing durable, high-gloss finishes for appliances and automotive parts. Adhesives & Lubricants: Precursor for hot-melt adhesives and high-grade diester synthetic lubricants.
Packaging & Storage	Packaging: 25kg Kraft Paper Bag / 500kg Jumbo Bag. Storage: Store in a cool, dry place. Keep container closed to prevent moisture absorption (hygroscopic).
