COA of Formula: C8H8O2In 2019 ,《Development of novel pyrazolones by using SiO2/ZnCl2 – green approach》 appeared in Journal of Chemical Sciences (Berlin, Germany). The author of the article were Neelima, G.; Lakshmi, K.; Sesha Maheswaramma, K.. The article conveys some information:
An efficient and green synthesis of substituted pyrazolone derivatives I [R = 2-MeO, 4-Cl, 3,4-di-MeO, etc.] was developed from 2,4-dinitrophenylhydrazine with aromatic aldehydes and Et acetoacetate in presence of silica-supported zinc chloride (SiO2/ZnCl2) as a recyclable Lewis acid catalyst. All the compounds I were tested for their antioxidant activity by using DPPH radical scavenging method. The results came from multiple reactions, including the reaction of 2-Methoxybenzaldehyde(cas: 135-02-4COA of Formula: C8H8O2)
2-Methoxybenzaldehyde(cas: 135-02-4) is found in cassia oil, cinnamon bark, and cinnamon bark oil. It is a clear colorless liquid with a strong aroma. It has been used to examine the acaricidal activity of Periploca sepium oil and its active component against Tyrophagus putrescentiae.COA of Formula: C8H8O2
