36886-76-7 Usage

General Description

3',6'-Dimethoxyfluoran, also known as N-Naphtholbenzeinthiazine, is a chemical compound mainly used in the industrial ink and dye sectors, especially in thermo/pH sensitive inks. It is particularly employed for its color-forming properties, and can induce a change in color when exposed to heat or changes in pH levels. It can appear either as white or slightly colored crystals or powder. Precautions need to be taken while handling this chemical, as prolonged exposure can lead to skin irritation or serious eye damage. Like many industrial chemicals, it should be kept away from heat, hot surfaces, sparks, open flames and other ignition sources. Its molecular formula is C23H16N2O4S.

Check Digit Verification of cas no

The CAS Registry Mumber 36886-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,8,8 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 36886-76:
(7*3)+(6*6)+(5*8)+(4*8)+(3*6)+(2*7)+(1*6)=167
167 % 10 = 7
So 36886-76-7 is a valid CAS Registry Number.

5-hydroxymethylfurfural- and fluorescein-fused fluorescence probe of mast cells (RBL-2H3): Synthesis, photophysical properties, and bioimaging

Huang, Limin,Wei, Di,Wu, Zibo,Hou, Yajing,Xie, Yitong,Liu, Zhenru,Wang, Cheng,Che, Delu,Lei, Yibo,He, Huaizhen

, p. 1963 - 1971 (2018)

A fluorescent probe (Fluo-HMF) was developed via introduction of a furfural moiety into the fluorescein molecular skeleton, aiming at specially labeling cell membrane of mast cells. To illustrate its specificity, we designed and synthesized a series of fluorescent compounds based on fluorescein molecular skeleton. The fluorescent properties of Fluo-HMF were investigated, which were in accordance with theoretical calculations. Compared with other fluorescein derivatives, Fluo-HMF could specially label RBL-2H3 cells. The results suggested that Fluo-HMF could be used as a fluorescent probe for bioimaging on some related research of allergic mechanism.

NbCl5-Promoted Synthesis of Fluorescein Dye Derivatives: Spectroscopic and Spectrometric Characterization and Their Application in Dye-Sensitized Solar Cells

da Silva, Bruno Henrique Sacoman Torquato,Bregadiolli, Bruna Andressa,Graeff, Carlos Frederico de Oliveira,da Silva-Filho, Luiz Carlos

, p. 261 - 269 (2017/03/07)

Fluorescein has several applications owing to its properties, such as high molar absorptivity, high fluorescence quantum yield, high photostability, and wavelengths of absorption and emission in the visible region. The syntheses of fluorescein derivatives between phenol and anhydride derivatives by using NbCl5 as a Lewis acid is described. The products have high yields and short reaction times are observed. The study of the UV/Vis and fluorescence spectra of these derivatives and their application in dye-sensitized solar cells is also described.
