5-(tert-Butyl)-4-hydroxyisophthalaldehyde(cas: 153759-59-2) belongs to phenols.Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according to the IUPAC Gold Book).HPLC of Formula: 153759-59-2

The author of 《Synthesis of 3,6-epoxy[1,5]dioxocines from 2-hydroxyaromatic benzaldehydes》 were Sashidhara, Koneni V.; Kumar, Abdhesh; Rao, K. Bhaskara. And the article was published in Tetrahedron Letters in 2011. HPLC of Formula: 153759-59-2 The author mentioned the following in the article:

Convenient and facile one step synthesis of medicinally relevant 3,6-epoxy[1,5]dioxocines e. g., I from 2-hydroxyarom. benzaldehydes is described. The scope of the method was validated by examining the use of both electron rich and electron-deficient 2-hydroxyarom. benzaldehydes. After reading the article, we found that the author used 5-(tert-Butyl)-4-hydroxyisophthalaldehyde(cas: 153759-59-2HPLC of Formula: 153759-59-2)
