white or gray to tan powder | [Uses]
Chromotropic acid disodium salt dihydrate may be employed as a chromogenic reagent for the quantification of dipyrone in various pharmaceutical preparations. | [Uses]
4,5-Dihydroxynaphthalene-2,7-disulfonic acid disodium salt dihydrate, is used to improve the visualization of trichothecenes on developed TLC plates. It serves as an intermediate in the production of dyes, pigments, chelating reagents, sulfonic and sulfinic acids. | [General Description]
Chromotropic acid disodium salt dihydrate is a tan colored sodium salt. | [Purification Methods]
Recrystallise it from H2O or H2O by adding EtOH. It complexes with Ag, ClO3-, Cr, Hg, NO2 , -NO3 and Ti. [Beilstein 11 H 72, 11 I 307, 11 II 174, 11 III 174, 11 IV 576.] |
