C₃₆H₆₆N₆O₆^99mTc Technetium(1+)-^99mTc, hexakis(1-isocyano-2-methoxy-2-methylpropane)-, (OC-6-11)-;
Hexakis(2-methoxy-2-methylpropyl isocyanide)[^99mTc]technetium(1+) [109581-73-9]

DEFINITION

Technetium Tc 99m Sestamibi Injection is a sterile, aqueous solution of tetrakis (2-methoxy-isobutyl isonitrile) copper (I) tetrafluoroborate that is labeled with radioactive technetium (^99mTc) suitable for intravenous administration. It contains NLT 90% and NMT 110% of the labeled amount of ^99mTc as a complex with sestamibi, expressed in megabecquerels (or in millicuries) per milliliter at the time indicated in the labeling. Other chemical forms of radioactivity are NMT 10% of the total radioactivity. It contains reducing agents, a buffer, and an inert filler.
