Description

2-Methyl Decanal is a high-purity, branched-chain aliphatic aldehyde with a distinctive, powerful, and waxy-orange peel-like odor. This compound is a key intermediate and fragrance ingredient valued for its ability to impart unique olfactory characteristics and modify scent profiles. It is essential for manufacturers in the fragrance and flavor industry, as well as for chemical synthesis in research and development.

Application

• Fragrance & Flavor Industry: A primary building block for creating complex citrus, waxy, and aldehydic notes in perfumes, cosmetics, soaps, and fine fragrances.
• Flavoring Agent: Used to enhance or replicate orange, mandarin, and other citrus flavors in food products and beverages.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis for the production of more complex molecules, including pharmaceuticals and agrochemicals.
• Aroma Chemicals: A key component in the manufacture of specialty aroma chemicals for household and industrial air care products.
• Research & Development: Utilized in R&D laboratories for studying reaction pathways of aldehydes and developing new synthetic methodologies.

Quality Control

Our 2-Methyl Decanal is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC analysis for purity and identity confirmation, to ensure it meets exacting specifications for the fragrance and flavor industries. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee supply reliability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is easily oxidized; for long-term storage, an inert atmosphere (nitrogen blanket) is recommended to maintain optimal purity and shelf life. Keep away from strong oxidizing agents.
