147-81-9 Usage
Description
DL-Arabinose, a white fine crystalline powder, is a sugar alcohol that exists in two enantiomeric forms, D-arabinose and L-arabinose. It is a naturally occurring monosaccharide found in various plants and is known for its unique properties and potential applications in different industries.
Uses
Used in Pharmaceutical Industry:
DL-Arabinose is used as a building block for the polysaccharide (CCPa-1) from the fungus Coprinus comatus Gray, which has potential applications as a natural antitumor agent with immunomodulatory activity. This makes it a valuable component in the development of novel cancer treatments and therapies.
Used in Chemical and Biochemical Research:
DL-Arabinose is utilized in physicochemical studies to measure properties such as dielectric relaxation. It is also employed in the chiral separation of sugars, which is crucial for understanding the stereochemistry of various biochemical processes and the development of enantiomerically pure compounds.
Used in Microbiology:
DL-Arabinose serves as a culture medium for certain bacteria, providing a suitable environment for their growth and reproduction. This application is essential in various research and industrial processes that require the cultivation of specific bacterial strains.
Check Digit Verification of cas no
The CAS Registry Mumber 147-81-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 147-81:
(5*1)+(4*4)+(3*7)+(2*8)+(1*1)=59
59 % 10 = 9
So 147-81-9 is a valid CAS Registry Number.

Racemic ribose is a valuable starting material for investigations of the origins of biomolecular homochirality. It can be synthesized in seven steps starting from D-glucose.
THE FORMOIN REACTION
Castells, Josep,Lopez-Calahorra, Francisco,Geijo, Fernando
, p. 197 - 208 (2007/10/02)
The formoin reaction, i.e., the autocondensation of formaldehyde in an aprotic solvent catalysed by the conjugate base of a thiazolium ion, has been studied in detail.Glucose, galactose, dihyroxyacetone dimer, xylose, and arabinose have been identified as products.The influence of catalysts, temperature, basicity, and reaction time is documented.N,N-Dimethylformamide is a more convenient solvent than ether, benzene, or diglyme.Ethyldi-isopropylamine affords better yields of carbohydrate material than triethylamine.At =60 deg, aldol condensations are reduced to a minimum.After 1-2 h of reaction (depending on the conditions), the yields begin to decrease and become zero after ca. 24 h.
