Import D(+)-Malic Acid — Buy in Bulk from Supplier in China

D(+)-malic acid is supplied as white crystals or a white crystalline powder, identified by CAS No. 6915-15-7 and molecular formula C4H6O5 (molecular weight 134.09 g·mol‑1). The FCCIV 1996 grade listed by the supplier shows an assay of 99.0 %‑100.5 %, optical purity of 98 % by chiral HPLC and a specific rotation between +1.6° and +2.6° (c=8.5 g·100 mL‑1, H2O). Heavy‑metal limits are 2 mg·kg‑1 for arsenic and 20 mg·kg‑1 for lead, with additional max values for chloride, sulfate, fumaric acid and maleic acid as defined in the specification sheet.

The product conforms to the FCCIV 1996 standard, which is commonly used for food‑grade and pharmaceutical‑grade malic acid. Typical FCCIV batches also maintain moisture below 0.5 % and are packaged in sealed fibre drums or 25 kg polyethylene bags to protect against humidity. The supplier reports the material is freely soluble in water and alcohol, a property that aligns with standard industry expectations for this hydroxy‑dicarboxylic acid.

D(+)-malic acid is employed in flavour formulation, nutritional supplements, cosmetics and as an intermediate in pharmaceutical synthesis, attracting buyers such as food manufacturers, nutraceutical firms and contract chemical producers. The listing does not disclose price, minimum order quantity or lead time, so interested importers should request a formal quotation and confirm incoterms, payment method and any required certificates before placing an order.
