Import 3-Amino-2-Benzopyrone — Buy in Bulk from Supplier in China

3-amino-2-benzopyrone is a synthetic benzopyrone derivative with the CAS number 1635-31-0 and a molecular formula of C9H7NO2. Its molecular weight is 161.16 g/mol, and it carries the EINECS identifier 216-659-4 for regulatory traceability. This compound is supplied as a high-purity chemical reagent, with applications spanning pharmaceutical intermediates, dye synthesis, and specialty chemical manufacturing. The product is delivered as a crystalline solid under controlled conditions to maintain stability and consistency.

The structure features an amino group at the 3-position of the benzopyrone skeleton, which enhances its reactivity in organic synthesis. Typical grades for such compounds include reagent-grade purity above 98%, with residual solvents and heavy metals controlled to parts per million levels. Industry-standard testing for this category often includes HPLC for assay determination, GC-MS for volatile impurities, and Karl Fischer titration for moisture content. These methods ensure the compound meets the tight specifications required for downstream use in drug formulation or colorant production.

Pharmaceutical and agrochemical manufacturers source this intermediate for its role in synthesizing bioactive molecules, while dye producers use it to create stable colorants with improved lightfastness. Bulk buyers commonly request packaging in 25 kg fiber drums with inner polyethylene liners to prevent moisture ingress. Trade terms such as FOB Shanghai are standard, with certification to ISO 9001 typical for suppliers in this category. Buyers should confirm packaging compatibility with their processing equipment and storage conditions.
