585-99-9 Usage
Chemical Properties
White powder
Uses
Melibiose has been used in a study to improve the preparation of benzoylated ethyl 1-thioglycosides. It has also been used in a study to investigate the effect of water plasticization on the molecular mobility and crystallization tendency of amorphous disaccharides.
Definition
Different sources of media describe the Definition of 585-99-9 differently. You can refer to the following data:
1. A disaccharide con-
sisting of two glucose units in an alpha (1-
6)glycosidic linkage. It is an effector molecule that
permits activation of the lac operon by binding to
the repressor molecule.
2. A salt
that has a single molecule of WATER OF
CRYSTALLIZATION, such as sodium carbonate
monohydrate, Na2CO3.H2O.
3. monohydrate: A crystalline compoundhaving one mole of water permole of compound.
General Description
Melibiose is a carbon substrate.
Purification Methods
Melibiose crystallises as a hydrate from water or aqueous EtOH. The anomer is obtained by recrystallising 1g from a mixture of 0.35mL of H2O and 0.2mL of EtOH. It crystallises easily with m 179o and mutarotates from [] D 20 +166o to +142.3o (220minutes, c 4, H2O). Crystallisation from MeOH gives the anhydrous form which hydrates to the monohydrate in air. The anomer dihydrate m 85-86o mutarotates from [] D 20 +123.5o to +143.1o (c 4, H2O for anhydrous). [Fletcher & Diehl J Am Chem Soc 74 5774 1952, Beilstein 1 7 III/IV 3075, 17/7 V 206.]
Check Digit Verification of cas no
The CAS Registry Mumber 585-99-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,8 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 585-99:
(5*5)+(4*8)+(3*5)+(2*9)+(1*9)=99
99 % 10 = 9
So 585-99-9 is a valid CAS Registry Number.
