Description

Structurally, 62625-21-2 Phenol, 4,4'-(3H-2,1-benzoxathiol-3-ylidene)bis(5-methyl-2-(1-methylethyl)-, S,S-dioxide, monosodium salt Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis(5-methyl-2-(1-methylethyl)-, monosodium salt Sodium hydrogen 4,4'-(3H-2,1-benzoxathiol-3-ylidene)bis(5-methyl-2-(1-methylethyl)phenolate) S,S-dioxide Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis(5-methyl-2-(1-methylethyl)-, sodium salt (1:1) EINECS 263-650-6 Thymol blue sodium salt Thymol Blue, water soluble (C27H47O5SNa) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 506.72 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
