Product Name:D-Lactal
English Name:D-Lactal
CAS No.:65207-55-8
Aliases:D-LACTAL, Lactal
Molecular Formula:C12H20O9
Physical Properties:White to off-white crystalline powder, readily soluble in water, DMSO and DMF, soluble in ethanol, slightly soluble in chloroform and diethyl ether. Melting point approximately 170°C (decomposition), specific optical rotation [α]D20 approximately +22° (c=1, water). Sensitive to light and moisture, unstable under acidic conditions; store tightly sealed, protected from light, at low temperature in a dry place.
Uses:Mainly used as a chiral intermediate in glycochemistry and pharmaceutical synthesis for the preparation of glycosides, oligosaccharides, and other carbohydrate derivatives. In biochemical research, it serves as a glycosyl donor precursor for the synthesis of biologically active natural products and their analogs.
Technical Specifications:
Purity (HPLC): ≥98%
Appearance: white to off-white powder
Molecular weight: 308.28
Loss on drying: ≤1.0%
Storage: keep tightly sealed, protected from light, at low temperature, in a dry place
