Product Name:5,6-O-Isopropylidene-L-ascorbic acid
English Name:5,6-O-Isopropylidene-L-ascorbic acid
CAS No.:15042-01-0
Aliases:5,6-Isopropylidene-L-ascorbic acid, L-Ascorbic acid 5,6-acetonide, (+)-5,6-O-Isopropylidene-L-ascorbic acid
Molecular Formula:C9H12O6
Physical Properties:White to off-white crystalline powder with acidic and reducing properties. Soluble in methanol, ethanol, DMF and DMSO; slightly soluble in water; almost insoluble in diethyl ether. Slowly oxidizes and discolors upon exposure to light and heat; relatively stable under acidic conditions.
Uses:Mainly used as an intermediate for synthesizing L-ascorbic acid derivatives, especially for selective protection of the 5,6-diol to prepare ascorbic acid esters, ethers, phosphate esters and other vitamin C derivatives. It is also used as a chiral building block in the synthesis of pharmaceuticals and fine chemicals.
Technical Specifications:
Formula: C9H12O6; Molecular weight: 216.19
Appearance: white to off-white crystalline powder
Melting point: approximately 218-220 °C (dec.)
Specific rotation: [α]D20 approximately +20° to +30° (c=1, methanol)
Assay (HPLC): ≥98%
