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 Investigations on dendrimer space reveal solid and liquid tumor growth-inhibition by original phosphorus-based dendrimers and the corresponding monomers and dendrons with ethacrynic acid motifs, published in 2015, which mentions a compound: 56621-48-8, mainly applied to Edecrin phosphorus dendrimer dendron antiproliferative epidermal carcinoma leukemia growth, Reference of 4-(Piperazin-1-yl)phenol.
The well-known reactive diuretic ethacrynic acid (EA, Edecrin), with low antiproliferative activities, was chem. modified and grafted onto phosphorus dendrimers and the corresponding simple branched phosphorus dendron-like derivatives affording novel nanodevices showing moderate to strong antiproliferative activities against liquid and solid tumor cell lines, resp.
After consulting a lot of data, we found that this compound(56621-48-8)Reference of 4-(Piperazin-1-yl)phenol can be used in many types of reactions. And in most cases, this compound has more advantages.
