591-28-6 Usage
Description
4-Thiouracil is a site-specific, photoactivatable probe used to detect RNA structures and nucleic acid-nucleic acid contacts. It absorbs ultraviolet light >300 nm and, in the presence of oxygen, acts as an energy donor to produce singlet oxygen by triplet-triplet energy transfer. The highly reactive oxygen species then reacts readily with 4-thiouracil, leading to the production of uracil and uracil-6-sulfonate, which is fluorescent at a wavelength of ~390 nm. 4-Thiouracil is used as a T. gondii uracil phosphoribosyltransferase substrate to produce 4-thiouridine monophosphate, which can ultimately be incorporated into RNA.

Uses
Different sources of media describe the Uses of 591-28-6 differently. You can refer to the following data:
1. 4-Thiouracil is suitable reagent employed in Schneider′s media for the embryos during RNA extraction. It may be employed as reagent for the Northwestern blotting technique.
2. 4-Thiouracil is a derivative of Uracil (U801000), which is a nitrogenous base in RNA nucleic acid. 4-Thiouracil is used for tagging in cell type-specific RNA isolation from intact complex tissues.
Check Digit Verification of cas no
The CAS Registry Mumber 591-28-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 591-28:
(5*5)+(4*9)+(3*1)+(2*2)+(1*8)=76
76 % 10 = 6
So 591-28-6 is a valid CAS Registry Number.

A one-pot, water compatible synthesis of pyrimidine nucleobases under plausible prebiotic conditions

Herein, we report a new prebiotically plausible pathway towards a pyrimidine nucleobase in continuous manner. The route involves simultaneous methylation and carbamoylation of cyanoacetylene-derived α,β-unsaturated thioamide with N-methyl-N-nitrosourea (MNU) in aqueous media. This provides S-methylpyrimidinone in one-pot, which can be converted into a variety of 4-substituted pyrimidine nucleobases including cytosine and uracil.
