In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called cis-4-[[[(2-Chloroethyl)nitrosoamino]carbonyl]methylamino]cyclohexanecarboxylic acid, a nitrosourea with latent activity against an experimental solid tumor, published in 1984, which mentions a compound: 3685-23-2, mainly applied to cyclohexanecarboxylic acid nitrosoaminocarbonylamino; nitrosoaminocarbonylaminocyclohexanecarboxylate preparation antitumor; nitrosourea antitumor, HPLC of Formula: 3685-23-2.
The title compound (I) was synthesized in five steps from cis-4-aminocyclohexanecarboxylic acid via the N-tosylated intermediate II. I, which is incapable of the facile decomposition that characterizes the clin. useful nitrosoureas, effected a significant cure rate of both early and established murine Lewis lung carcinoma, even though its in vitro half-life was ∼5.5 times that of the unmethylated parent compound This is the first observation of latent activity of a nitrosourea against an exptl. solid tumor.
After consulting a lot of data, we found that this compound(3685-23-2)HPLC of Formula: 3685-23-2 can be used in many types of reactions. And in most cases, this compound has more advantages.
