How should Trisodium 2,2'-({5-[3-(3-{[(carboxylatomethyl)(carboxymethyl)amino]methyl}-4-hydroxy-5-methylphenyl)-2,2-dioxido-3H-1,2-benzoxathiol-3-yl]-2-hydroxy-3-methylbenzyl}imino)diacetate (CAS: 3618-43-7) be stored?

Trisodium 2,2'-({5-[3-(3-{[(carboxylatomethyl)(carboxymethyl)amino]methyl}-4-hydroxy-5-methylphenyl)-2,2-dioxido-3H-1,2-benzoxathiol-3-yl]-2-hydroxy-3-methylbenzyl}imino)diacetate should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a tightly sealed container and stored at room temperature (15-25°C) to maintain its stability. Avoid exposure to moisture and maintain good ventilation to prevent degradation.
