beta-D-Galactose pentaacetate , its cas register number is 4163-60-4. It also can be called beta-D-Galactose pentaacetate (VAN) ; and 1,2,3,4,6-Penta-O-acetyl-beta-D-galactopyranose; Penta-O-acetyl-beta-D-galactopyranose . Its classification code is TSCA Flag P [A commenced PMN (Premanufacture Notice) substance].
beta-D-Galactose pentaacetate (CAS NO.4163-60-4) could be stable under normal temperatures and pressures. It should avoid the condition like incompatible materials. It is not compatible with strong oxidizing agents. And also prevent it to broken down into hazardous decomposition products: carbon monoxide, carbon dioxide. However, its hazardous polymerization will not occur.
