O-Cresolphthalein CAS 596-27-0
O-cresol phthalein ichena kusvika kuchiedza checrystalline poda. Kunyungudika 216 ~ 217 ℃. Inonyungudika mudoro, ether uye glacial acetic acid, inonyungudika zvishoma mumvura, isinganyunguriki mubenzene, inonyungudika mu dilute alkali. Inoshandiswa senge acid-base chiratidzo mune analytical chemistry. Iine chimiro chakafanana chemakemikari uye chemuviri uye chemikemikari zvinhu kune phenolphthalein, uye ruvara rwayo ruvara rwemavara ndeye 8.2 (isina ruvara) -9.8 (tsvuku) (Phenolphthalein color discoloration range is 8.2-10). Chimiro chayo cheasidhi haina ruvara rwelactone fomu, uye chigadziko chayo chimiro chequinone uye chinoita chitsvuku.
