2,5-Dimethyl-2,3-dihydrofuran is an important oxygen-containing heterocyclic fine chemical intermediate widely used in pharmaceutical synthesis, flavor & fragrance and pesticide raw material industries. Its saturated dihydrofuran ring is easy to undergo ring-opening, oxidation and addition reactions to build multi-carbon aliphatic chain and cyclic ether structures. In API manufacturing, it serves as core starting material for synthesizing cardiovascular drugs, anti-inflammatory intermediates and chiral alcohol raw materials via acid hydrolysis into 2,5-hexanediol. For fragrance industry, it is applied to prepare fruit flavor additives with apple and sweet cream aroma after oxidation derivatization, widely used in food essence formulation. Agrochemical factories adopt it to synthesize high-selectivity herbicide and insecticide intermediates through epoxidation and amination reactions. Organic chemistry labs use it as standard substrate for heterocyclic ring-opening reaction research and catalyst screening. Commercial goods normally packed in 160L galvanized iron drum for bulk export, small lab sample in 250ml fluorinated bottle.

GHS:H224,H315,H319,H335;Signal Word:Danger, Highly Flammable Liquid Extremely flammable with low flash point, vapor forms explosive mixture with air under room temperature. Direct skin contact causes dryness and irritation, wash polluted skin with plenty of running water for over 15 minutes; liquid splashing into eyes triggers severe irritation and lacrimation, continuous eye rinse with clean water and seek medical care in case of persistent discomfort. Inhalation of high-concentration vapor irritates respiratory tract and induces dizziness and nausea; all operation must be performed in explosion-proof fume hood with nitrile gloves, anti-splash goggles and organic vapor respirator, strictly eliminate open fire and static electricity around operation area. Store separately from strong acid, oxidants and food raw materials in explosion-proof cold storage warehouse. Waste liquid belongs to hazardous chemical waste, must be collected and disposed by certified professional waste treatment company complying with local environmental protection regulations, forbidden direct drainage into sewer and soil.
