873-83-6 Usage

Chemical Properties

cream to light brown crystalline powder

Safety Profile

Moderately toxic by parenteralroute. When heated to decomposition it emits toxic fumesof NOx.

Purification Methods

Purify the aminouracil by dissolving it in 3M aqueous NH3, filtering hot, and adding 3M formic acid until precipitation is complete. Cool, filter off (or centrifuge), wash well with cold H2O, then EtOH and dry it in air. Dry it further in a vacuum at ~80o. [Barlin & Pfeiderer J Chem Soc (B) 1424 1971, Beilstein 25 III/IV 4107.]

Check Digit Verification of cas no

The CAS Registry Mumber 873-83-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 873-83:
(5*8)+(4*7)+(3*3)+(2*8)+(1*3)=96
96 % 10 = 6
So 873-83-6 is a valid CAS Registry Number.

Short time modification of carboxylated multi-wall nanotubes with amino uracil derivative

Zomorodbakhsh, Shahab,Mirza, Behrooz,Yazdizadeh, Shima,Tavahodi, Ehsan

, p. 1379 - 1383 (2014)

In this study, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by Amino uracil derivative via microwave- assisted amidation method have been investigated.The functionalized MWNTs were characterized by Fourier Transform Infrared spectroscopy (FT-IR), Raman spectroscopy, elemental analysis and scanning electron microscopy (SEM). The major advantage of this procedure is reducing the reaction time to the order of minutes and the amidation was completed in one step as compared to two in the conventional approach. The acid chloride formation step was eliminated here.

Preparation method for 4-amino-2,6-dimethoxypyrimidine

-

Paragraph 0027-0030; 0041-0043, (2020/05/02)

The invention discloses a preparation method for 4-amino-2,6-dimethoxy pyrimidine. According to the method, with cyanoacetate and urea as raw materials, the 4-amino-2,6-dimethoxypyrimidine is synthesized through a cyclization and methylation two-step method. The preparation method provided by the invention shortens production process steps, optimizes reaction conditions, improves the reaction yield, solves the problem that a large amount of colored phosphorus-containing wastewater is generated in the original process, and provides an effective way for efficient green industrial production of the 4-amino-2,6-dimethoxypyrimidine.

Novel riboflavin-inspired conjugated bio-organic semiconductors

Richtar, Jan,Heinrichova, Patricie,Apaydin, Dogukan Hazar,Schmiedova, Veronika,Yumusak, Cigdem,Kovalenko, Alexander,Weiter, Martin,Sariciftci, Niyazi Serdar,Krajcovic, Jozef

, (2018/09/12)

Flavins are known to be extremely versatile, thus enabling routes to innumerable modifications in order to obtain desired properties. Thus, in the present paper, the group of bio-inspired conjugated materials based on the alloxazine core is synthetized using two efficient novel synthetic approaches providing relatively high reaction yields. The comprehensive characterization of the materials, in order to evaluate the properties and application potential, has shown that the modification of the initial alloxazine core with aromatic substituents allows fine tuning of the optical bandgap, position of electronic orbitals, absorption and emission properties. Interestingly, the compounds possess multichromophoric behavior, which is assumed to be the results of an intramolecular proton transfer.
