Cytidine - 5' monophosphate
-
Empirical chemical formula: C9 H14N3 O8 P
In addition the compound must be of the 5 species, ie the monophosphate structure is attached to the fifth carbon in the central structure.
-
Molecular weight: 323.20
-
Structure/Physical character: Occurs as a colourless or white crystal or as a white crystalline powder. It is odourless and has a characteristic slightly acidic taste.
-
Solubility: Very slightly soluble in water; practically insoluble in alcohol.
Guanosine - 5' monophosphate disodium salt
-
Empirical chemical formula: C10 H12N5 Na2 O8 PΒ· 7.OH2O
In addition the compound must be of the 5 species, ie the disodiummonophosphate structure is attached to the fifth carbon in the central structure.
-
Molecular weight: 533.26
-
Structure/ Physical character: Occurs as a colourless or white crystal or as a white crystalline powder. It is odourless and has a characteristic taste.
-
Solubility: 20 g is soluble in 100g of water at 20Β°C; becomes gelatinous in acid liquids under the identical conditions
TESTING REQUIREMENTS FOR NUCLEOTIDES
-
Physical inspection: white crystals or crystalline powder
-
Identification:
a) Ultraviolet absorbance: a 1 in 12,500 solution of the powder in 0.01N hydrochloric acid exhibits an absorbance maximum at:
Absorbance Nucleotide 250+- 2nm Inosine - 5' monophosphate disodium salt 260+- 2nm Uridine - 5' monophosphate disodium salt 257+- 2nm Adenosine- 5' monophosphate 280+- 2nm Cytidine - 5' monophosphate 256+- 2nm Guanosine - 5' monophosphate disodium salt
