Usage
●A corrosion inhibitor for battery anodes, e.g., metals such as zinc, lead, and the like, in
primary battery cells, comprises a quaternary ammonium salt, particularly, tetraalkyl ammonium chloride.More preferably Tetraheptyl ammonium chloride.
●Used in hybridization solutions of mixed oligonucleotides. In solutions with TMAC, the Tm(melting temperature) of a hybrid is dependent on its length, not its base composition.
TMAC,
●Used in probing PCR (polymerase chain reaction) products for the analysis of polymorphisms with allele-specific oligonucleotides.
Packing and Storage
● should store at RT, Keep container dry,Keep in a cool place.
● Ground all equipment containing material. Keep container tightly closed.Combustible materials should be stored away from extreme heat and away from strong oxidizing agents
