Isonipecaine means any substance identified chemically as 1-methyl-4-phenyl-piperidine-4-carboxylic acid ethyl ester or any salt of such substance by whatever trade name designated.

Ketobemidone means any substance identified chemically as 4-3-hydroxyphenyl-1-methyl-4-piperidylethyl ketone hydrochloride or any salt of such substance by whatever trade name designated. Ethyl alcohol is a great choice for cleaning electronics in the laboratory because its inexpensive mineral-free and evaporates quickly. While ethanol isnt a strong solvent it is typically sufficiently powerful to clean sensitive electronics which may have accumulated light layers of corrosion or dirt.

METHYL ETHYL KETONE ETHANOL and TOLUENE in blood 8002. Offers strong solvency and fast evaporative properties. With high purity they are listed as a non-hazardous air pollutant under US.

A clear colorless and volatile material with a light odor that possesses physico-chemical and solvency properties similar to those of ethyl alcohol making it miscible with water and soluble. The secondary amine which has one methyl group and one ethyl group attached to nitrogen is named N-methylethanamine the two carbon chain is used as the main chain in preference to the one carbon chain. Note the usage of the letter N to designate that the methyl substitutent is attached to nitrogen.

If one R group is methyl a second is ethyl and a third is propyl the amine would be named N.
