Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Electric Literature of C4H5ClO3

Electric Literature of C4H5ClO3In 2019 ,《Design, synthesis and biological evaluation of novel 7-amino-[1,2,4]triazolo[4,3-f]pteridinone, and 7-aminotetrazolo[1,5-f]pteridinone derivative as potent antitumor agents》 appeared in European Journal of Medicinal Chemistry. The author of the article were Hou, Yunlei; Zhu, Liangyu; Li, Zhiwei; Shen, Qi; Xu, Qiaoling; Li, Wei; Liu, Yajing; Gong, Ping. The article conveys some information:

To develop novel therapeutic agents with anticancer activities, two series of novel 7-amino-[1,2,4]triazolo[4,3-f]pteridinone, and 7-aminotetrazolo[1,5-f]pteridinone derivatives were designed and synthesized. All compounds were tested for anti-proliferative activities against five cancer cell lines. The structure-activity relationships (SARs) studies were conducted through the variation in two regions, the moiety of A ring and the terminal aniline B on pteridinone core. 1-Methyl-1,2,4-triazole derivative I with 2,6-dimethylpiperazine showed the most potent antiproliferative activity against A549, PC-3, HCT116, MCF-7 and MDA-MB-231 cell lines with IC50 values of 0.16 μM, 0.30 μM, 0.51 μM, 0.30 μM, and 0.70 μM, resp. Combined with the results of the mol. docking and enzymic studies, the PLK1 was very likely to be one of the drug targets of compound I. Furthermore, to clarify the anticancer mechanism of compound I, further explorations in the bioactivity were conducted. The results showed that compound I obviously inhibited proliferation of A549 cell lines, induced a great decrease in mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells, and arrested G1 phase of A549 cells.
