Is Blue 1 a dye?

Blue 1, also called Brilliant Blue, is the more common of the two FDA-approved blue dyes and one of the oldest approved dyes in use.

What is the molar mass of Erioglaucine?

Thermo Scientific Erioglaucine disodium salt, pure

How do you calculate the molar mass of a dye?

The molar absorptivity of the dye is the slope (A = ε b c or y = mx) since b = 1. Thus, molar absorptivity = ε = 248 L mol-1 cm-1.

What is the molar absorptivity of the blue dye?

To demonstrate the use of evanescent sensing for liquid concentration measurements, 400 nl droplets of aqueous solutions of FD&C Blue 1 dye (molar absorptivity = 1.38 x 10-5 M-1 cm-1) were transported across the beam path at a speed of 250 µm/s.

Is Blue 1 an azo dye?

Direct Blue 1 is an organic compound that is one of many azo dyes. This salt is used as a substantive dye for textiles with high contents of cellulose, i.e. cotton. It is prepared by the azo coupling of the aminonaphthalene and diazotized derivative of o-dianisidine.

What is the molecular weight of red dye?

650.6
Red dye I

What is the difference between Blue 1 and Blue 1 lake?

Blue 1, also called FD&C Blue No. 1, is a synthetic color that is subject to certification by the Food and Drug Administration (FDA). Blue 1 Lake is a water insoluble form of Blue 1 that is made from the certified color.

What is Erioglaucine dye?

C.I.No.42090 Erioglaucine is a widely used acid aminotriphenylmethane dye of an intense blue colour.

What is the molar mass of oxygen?

How many molecules of water are in a unit of methylene blue?

The hydrated form has 3 molecules of water per unit of methylene blue. Methylene blue has a pH of 6 in water (10g/l) at 25 °C (77 °F). This compound is prepared by oxidation of dimethyl-4-phenylenediamine in the presence of sodium thiosulfate: Absorption spectrum of methylene blue, in terms of the molar extinction coefficient (base 10 logarithm).

What is the color of a blue solution when oxidized?

Solutions of this substance are blue when in an oxidizing environment, but will turn colorless if exposed to a reducing agent. The redox properties can be seen in a classical demonstration of chemical kinetics in general chemistry, the ” blue bottle ” experiment.

How do you test for free dye in methylene blue?

Methylene blue solution is successively added to fine aggregate which is being agitated in water. The presence of free dye solution can be checked with stain test on a filter paper. In biology methylene blue is used as a dye for a number of different staining procedures, such as Wright’s stain and Jenner’s stain.

What is the use of methylene blue in organic chemistry?

Methylene blue is also a photosensitizer used to create singlet oxygen when exposed to both oxygen and light. It is used in this regard to make organic peroxides by a Diels-Alder reaction which is spin forbidden with normal atmospheric triplet oxygen.
