Import 5-Methyl-2-Hepten-4-One — Buy in wholesale FOB from Supplier in China

Wuhan Yuan Cheng GongChuang Technology Co.Ltd supplies 5-methyl-2-hepten-4-one, an unsaturated ketone with CAS registry number 81925-81-7, manufactured in Wuhan, Hubei province, China. The material is offered at an assay of 97 percent against an enterprise standard, packaged in 1 kg drums according to the source data. Its molecular formula is C8H14O with a molecular weight of 126.1962 g per mol. The compound carries the trivial name filbertone and is recognised for its characteristic hazelnut-like odour profile, making it valuable in flavour and fragrance applications rather than bulk industrial chemical use.

The structural backbone is a seven-carbon chain with a ketone at carbon 4, a trans double bond between carbons 2 and 3, and a methyl substituent at carbon 5. The stereochemical descriptor (2E,5R) identifies the enantiomerically relevant form for odour activity, though the supplier does not state whether the material is a single enantiomer or racemic mixture. Purity at 97 percent leaves scope for trace aldehydes, residual solvent, or positional isomers such as 4-methyl-2-hepten-4-one. Typical enterprise standards for flavour-grade ketones specify limits on water content, residual solvent, and colour as measured by Hazen or Gardner scale, though these parameters are not listed in the source and should be requested.

Primary buyers include flavour houses, fragrance compounders, and research institutions requiring organoleptically active molecules. The 1 kg drum format suggests small-batch or sample-scale supply rather than bulk tanker shipment, which buyers should confirm if scaling to commercial volumes. Applications span nut flavour reconstitution, baked goods, and confectionery top-notes. Before import, confirm with Wuhan Yuan Cheng GongChuang Technology whether the material is classified as a dangerous good under UN regulations, what safety data sheet revision is available, and whether the enterprise standard maps to any recognised pharmacopoeial or FEMA/GRAS reference.

Wuhan Yuan Cheng GongChuang Technology Co.Ltd is registered at Qianjiajie, Wuhan, Hubei province, postal code 432000, China. The supplier holds a Harbor trust tier classification. The listing records a response rate of 0.00 percent and zero average response hours, indicating no platform-mediated enquiry responses during the measurement window. Buyers should therefore initiate direct contact via the supplier's official channels to confirm active trading status and current product availability before relying on the listing for procurement planning.

The company operates from Wuhan, a major centre for chemical synthesis and pharmaceutical intermediates in central China, with access to the Yangtze River logistics corridor. The source description provides no information about factory ownership, reactor capacity, R&D personnel, annual turnover, or named customers, so any such claims from third-party sources should be verified independently. The product range appears to focus on fine chemicals and specialty ketones, though the full catalogue is not detailed in the available data. Buyers should request a current manufacturing licence, safety data sheet, and certificate of analysis for the specific batch before committing to purchase.
