Uses
Used in Pharmaceutical Industry:
Calcium D-arabonate is used as an intermediate in the synthesis of D-erythroascorbic acid from D-glucose. D-erythroascorbic acid, also known as D-erythorbic acid or D-isoascorbic acid, is a synthetic form of Vitamin C that has similar properties to the naturally occurring L-ascorbic acid. It is used as a nutritional supplement, antioxidant, and preservative in various pharmaceutical formulations.
Used in Food Industry:
Calcium D-arabonate is also used in the food industry as a source of D-erythroascorbic acid, which serves as a preservative, antioxidant, and nutrient enhancer. It helps to extend the shelf life of food products, maintain their quality, and provide essential nutrients to consumers.
Used in Cosmetic Industry:
In the cosmetic industry, calcium D-arabonate is used as a precursor for the synthesis of D-erythroascorbic acid, which is incorporated into various skincare and beauty products. D-erythroascorbic acid acts as an antioxidant, helping to protect the skin from environmental damage and promote a healthy, youthful appearance.
Used in Chemical Synthesis:
Calcium D-arabonate is also used as a versatile building block in the synthesis of various organic compounds and pharmaceuticals. Its unique chemical properties allow it to be easily modified and incorporated into a wide range of molecules, making it a valuable tool for chemists and researchers in the field of organic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 22373-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,7 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22373-09:
(7*2)+(6*2)+(5*3)+(4*7)+(3*3)+(2*0)+(1*9)=87
87 % 10 = 7
So 22373-09-7 is a valid CAS Registry Number.

Synthesis of D-erythroascorbic acid from D-glucose
Gan, Li-Xian,Seib, Paul A.
, p. 117 - 126 (2007/10/02)
Reaction of a 4:1 mixture of D-ribono- and D-arabinono-1,4-lactones with benzaldehyde and hydrochloric acid gave 59percent crystalline 3,4-O-benzylidene-D-ribono-1,5-lactone.This acetal was oxidized with manganese dioxide in acetone to its 2-keto-derivative (6) in 76percent yield.Acid-catalyzed methanolysis of 6 gave a syrupy mixture of products, which upon tautomerization in hot methanolic sodium acetate followed by removal of sodium ions gave 78percent D-erythroascorbic acid (7).The overall yield of 7 starting from D-glucose was 20percent.
