Products Usage
DL-Malic acid (MA) can be used:
1. As a dopant in the ammonium dihydrogen phosphate (ADP) crystal to improve the properties of ADP crystals.
2. To form a water-soluble complex, Nb-MA which can further react with LiCl to form lithium niobate (LiNbO3) powders.
3. As a monomer to synthesize a co-polymer, poly(DL-lactic acid-co-α,β-malic acid) (PLMA) with DL-lactic acid which can be coated over magnetic Fe3O4 nanoparticles after functionalizing with fluorescein isothiocyanate (FITC), to be used as a MRI T2-contrast agent.
Package And Storage
Package:
25kg/carton drum or as your requirements.
Remark: Chemical composition and size can be optimized by the customers' requirements
Storage:
The bulk material is hygroscopic and should be stored in an airtight container in a cool, dry place.
Safety Protection
Precautions for safe handling
NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
