Sodium dihydrogen phosphate monohydrate
CAS 10049-21-5
A simple buffer salt can determine whether two biological experiments are truly comparable.
Sodium dihydrogen phosphate monohydrate supplies H2PO4-, the acidic half of the common phosphate buffer pair. By adjusting its ratio to HPO4^2-, laboratories can set pH reproducibly and absorb small additions of acid or base. Its crystal water also matters because hydrated and anhydrous salts have different formula weights. A simple buffer salt can be essential experimental infrastructure.
