When US citizens are abroad and unable to obtain a medallion signature guarantee stamp, with prior notice of the substitution some financial institutions may accept a United States embassy seal in its place.
Phenyl-2-propanone (Compound 1), commonly referred to as P2P, is an intermediate precursor in the manufacture of d,l-amphetamine, d,l-methamphetamine, and other similar phenethylamines (Fig. 1).
P2P gets its namesake from phenyl-2-propanone, the intermediary molecule Walter White makes in process. P2P shares the same basic shape as methamphetamine and Sudafed. Like a skeleton key, it's a circular carbon loop (called a phenyl ring) with a short carbon neck bonded to a few teeth of clustered chemical groups.
