Quadratanium

a vial of Quadratanium

Quadratanium is a common compound of the Federation in the 24th century. This compound, in a finely ground state, could be procured from ship's stores.

One of the uses of quadratanium was as a topical ointment for the skin conditions of Soong-type androids. If ingested orally, the android will suffer a condition similar to unconsciousness in Humans.

When Lore stayed aboard the USS Enterprise-D in 2364, he visited ship's stores on deck four where he picked up a macrotool and samples of quadratantium. With the compound, Lore spiked a glass of champagne which he presented to his "brother" Data. Upon drinking the concoction, Data lapsed into unconsciousness. (TNG: "Datalore")

Though not identified by name, Lore's movements and the script make it clear that the "silver metal bits" Lore pours into Data's glass of champagne are pieces of finely ground quadratanium.
