Dihydropyran
Dihydropyran, chemically known as 3,4-dihydro-2H-pyran (C5H8O, CAS 110-87-2), is a heterocyclic organic compound used primarily as a protecting group reagent in synthetic chemistry. This listing specifies a technical grade with 98% assay, a boiling point of 86°C, and a density of 0.922 g/mL at 25°C. It is supplied as a colorless transparent liquid in 200 kg plastic drums, with an enterprise standard as the only declared specification.
The compound is valued for its reactivity in forming tetrahydropyran derivatives, which protect hydroxyl groups during multi-step syntheses in pharmaceutical and agrochemical manufacturing. Typical industrial use involves reactions with alcohols, amines, or nucleophiles under acidic conditions. The 98% purity level is standard for bulk synthesis applications; higher purities (>99%) are available but require special orders and are not listed here.
Buyers are typically fine chemical manufacturers, pharmaceutical intermediaries, and polymer researchers requiring a reliable source of this cyclic ether. The product is shipped in plastic drums under inert atmosphere to prevent moisture absorption. MOQ is 25 kg, and the price is listed at USD 31.35 per kg. Lead time, payment terms, and certification status are not provided and must be confirmed directly with the supplier.

Sourcing Dihydropyran from Wuhan Yuan Cheng GongChuang Technology Co.Ltd - China Import Guide
Before ordering, verify the assay method and impurity profile for your intended synthesis. Request a copy of the supplier's quality control protocol and confirm whether stabilizers are added. Check that the material is packaged in moisture-resistant drums with inert gas headspace. Do not accept material without a batch-specific certificate of analysis including water content and GC purity data.
Lead time is not stated but typically ranges from 15 to 25 days for chemical intermediates from this region. Incoterms are likely FOB Wuhan or Shanghai, but must be confirmed. Payment terms are not listed; common options include T/T in advance or LC at sight. Confirm if the supplier accepts third-party inspection and if pre-shipment testing is permitted.
Upon receipt, inspect drums for leaks, corrosion, or moisture ingress. Test a sample for water content via Karl Fischer titration and verify purity by GC analysis. Retain a sample for future reference. Ensure all documentation includes CAS number, batch number, and supplier signature. For regulatory compliance, request a GHS-compliant SDS and export declaration matching Chinese customs requirements.
