C₁₃H₁₆N₅O₈P; MW 401.3; λ_max 258 nm; ε 15000. Purity > 97% HPLC for mixture of axial and equatorial isomer. Membrane-permeant precursor of the second messenger cyclic AMP. After permeation and metabolic activation by esterases the polar cAMP is released which is trapped inside the cell and subsequently metabolized quickly, resulting in a pulse-type signal. Detailed technical information and updated reference list available. Reference: Schultz et al., J. Biol. Chem., 268, 6316 - 6322 (1993).

Biolog also offers Phosphate tris(acetoxymethyl)ester (PO₄-AM₃, Cat. No. P 030) which is recommended as control reagent in nucleotide-AM ester applications.
