Indigo Carmine Chemical Properties,Uses,Production

Description

Indigo carmine is indigotindisulfonate sodium, a marker dye used during cystoscopy and ureteral catheterization.
(1) Indigo carmine is also used in endoscopic procedures, lymph node and vessel delineation, and for tumor localization. Indigo carmine is an unapproved drug without FDA approved labeling.
(2) There is no single dye that can replace indigo carmine. Choice of alternative agent will depend on type of procedure and physician discretion, as well as product availability.
Indigo Carmine (IC) is the most common chemical dye for clothes dyeing, which is considered as a refractory molecule since it is required a rather strong chemical treatment for its elimination from the water waste. The presence of this dye in residuals causes notorious change of water color and smell even in very low concentration. Moreover, if some of this water reaches natural streams it can be toxic for aquatic living entities due to the formation of toxic compounds such as aromatic amines.

Chemical Properties

purple powder

Uses

5,5’Indigodisulfonic Acid Disodium Salt is a food additive that is widely used in the market. 5,5’Indigodisulfonic Acid Disodium Salt was also used as a dye for cationic cotton fabrics.

Definition

ChEBI: An organic sodium salt resulting from the formal condensation of indigo carmine (acid form) with two equivalents of sodium hydroxide. It is an indicator at pH 11.5-14, changing from blue to yellow.

Uses

Colorant for nylon, surgical sutures, foods and ingested drugs. As a reagent for functional kidney tests, for detection of nitrates, chlorates and in testing milk.

General Description

Indigo to dark blue powder.

Air & Water Reactions

Water soluble.

Reactivity Profile

Sensitive to light. Very sensitive to oxidizing agents. Color is readily discharged by nitric acid, chlorates, etc. Color of aqueous solutions fades on standing.

Fire Hazard

Flash point data for Acid Blue 74 is not available, but Acid Blue 74 is probably combustible.
