Disodium 5,5'-(2-(1,3-dihydro-3-oxo-2H-indazol-2-ylidene)-1,2-dihydro-3H-indol-3-one)disulphonate

인디고 카르민 C화학적 특성, 용도, 생산

개요

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.

화학적 성질

purple powder

화학적 성질

FD & C Blue No. 2 is principally the disodium salt of 2-( 1,3-dihydro-3-oxo-5-sulfo-2H-indol-2-ylidene)-2,3-dihydro3-oxo-lH-indole-5-sulfonic acid.
The colorant is a blue-brown to red-brown powder that dissolves in water to give a solution that is blue at neutrality, blue-violet in acid, and green to yellow-green in base. When dissolved in concentrated sulfuric acid, it yields a blue-violet solution that turns blue when diluted with water. It is soluble in 95% ethanol.
FD & C Blue No. 2 is used in dessert powders, bakery goods, cereals, snack foods, confectionery products, maraschino cherries, sausage, ice cream, sherbet, and dairy products. The color is also used in drug preparations.1 .

용도

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.

용도

Indigo Carmine (FD&C Blue #2) is a colorant. It has poor ph stability in that after 1 week at ph 3 and 5 it will appreciably fade, at ph 7 considerably fade, and at ph 8 fade completely. It is the least soluble of all food colors, with a solubility of 1.6 g in 100 ml of water at 25°c. Complete fading occurs in alkalis such as 10% sodium carbonate and 10% sodium hydroxide, with fading also occurring in 10% sugar systems. It has very poor light stability and oxidation stability, and moderate stability to heat; it has a deep blue hue with poor tinctorial strength. It is the only food color that has good resistance to reducing agents, but has very poor compatibility with food components. The major use is in pet food, but it is also used in candies, confections, and baked goods. The common name is indigotine.

용도

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.

정의

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.

제조 방법

3H-indol-3-one,2-(1,3-dihydro-3-oxo-2H-indol-2-ylidene)-1,2-dihydro?with strong sulfuric acid or trace fuming sulfuric acid products.

상표명

Indigo Carmine (Becton Dickinson Microbiology).

일반 설명

Indigo to dark blue powder.

공기와 물의 반응

Water soluble.

반응 프로필

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

화재위험

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

Purification Methods

Its solubility in H2O is 1g/100mL at 25o. It has been purified by dissolving in H2O, filtering and adding EtOH to cause the salt to separate. Wash the solid with EtOH, Et2O and dry in vacuo.

Properties and Applications

green light blue. Soluble in water for blue, slightly soluble in alcohol. The strong sulfuric acid is a deep blue light in purple, diluted into blue. In aqueous solution for green to yellow sodium hydroxide to join.
