Uses
Used in Agriculture:
Urea is used as a nitrogen-release fertilizer for promoting plant growth and development. It provides essential nitrogen to the soil, which is a vital nutrient for plant growth.
Used in Chemical Industry:
Urea serves as a starting material for the production of resins and plastics, such as urea-formaldehyde and melamine-formaldehyde resins. These resins are widely used in the manufacturing of adhesives, particleboard, and other composite materials.
Used in Pharmaceutical Industry:
Urea is used in the synthesis of barbituric acid, which is an important intermediate in the production of barbiturate drugs. Barbiturates are central nervous system depressants used for various medical applications, including sedation, anesthesia, and treatment of seizures.
Used in Paper Manufacturing:
Urea is employed in the manufacture of paper to improve its strength and durability. It is used in the production of urea-formaldehyde resins, which are applied as a size press size to enhance the paper's resistance to water and ink absorption.
Check Digit Verification of cas no
The CAS Registry Mumber 506-89-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 506-89:
(5*5)+(4*0)+(3*6)+(2*8)+(1*9)=68
68 % 10 = 8
So 506-89-8 is a valid CAS Registry Number.

VIRUCIDAL COMPOSITIONS AND METHODS
-
, (2021/12/17)
A biocidal/antiviral composition comprises a quaternary ammonium compound (QAC) in combination with a reagent that increases the cationic charge on the QAC to thereby increase the biocidal/antiviral effect of the QAC. In preferred aspects, the reagent is urea hydrochloride and the QAC is dialkyl dimethyl ammonium chloride.
Deep eutectic solvents as attractive media for CO2 capture

We report a family of deep eutectic solvents (DESs) consisting of various hydrogen bonding donor-acceptor pairs as CO2 capturing media. These DESs capture CO2via carbamate formation upon reaction between their hydrogen bonding donor units and CO2. Among the members tested herein, a DES made up of monoethanolamine hydrochloride-ethylenediamine exhibits an unprecedentedly high gravimetric uptake of 33.7 wt% with good initial kinetics (25.2 wt% uptake within 2.5 min) and recyclability. The given DES also shows sustainable performance in the presence of water, decent tolerance against temperature rise, and a relatively low heat of absorption which is attractive for regeneration. Even with the high gravimetric uptake, the DES has a far more suppressed corrosiveness compared to its pure monoethanolamine and ethylenediamine counterparts due to low oxygen/moisture permeability and the hydrogen bonding network that alleviates the corrosion redox cycle. The observed excellent properties in various key aspects of CO2 capture suggest that DESs are strong candidates to replace the conventional monoethanolamine-based scrubbing technology and are worth further exploration.
