The term "Concentration" denoted as "C=x% H2O after 1 hour" refers to the duration allowed for the material to dissolve in water to reach the specified concentration. This period was implemented because there were reproducibility issues observed when the solution's concentration was measured immediately after mixing.

General description
D-(+)-Glucuronic acid γ-lactone (Glucourono-γ-lactone, Glucurone or Glycurone) is a carbohydrate derivative. It converted into L-ascorbic acid in animals and human body. Its molecule contains two five-membered rings. Its crystal structure has been studied.[1]
Application
D-(+)-Glucuronic acid γ-lactone may be used in the following studies:
- As starting ragent in the synthesis of 2,3,4,-tris(tert.-butyldimethysilyl) glucuronic acid trichloroethylester, required for the preparation of 1-O-acyl glucuronide of the anti-inflammatory drug ML-3000.[2]
- Synthesis of optically active glucopyranoses.[3]
- Synthesis of long-chain alkyl glucofuranosides.[4]

Does the entry for "Concentration" described as "C=x% H2O after 1 hour" equate to Loss on Drying? If not, what does this specification indicate?
