1240-72-8 Usage
General Description
1,3-bis(2,5-dimethoxyphenyl)urea, also known as DMPU, is a chemical compound that is commonly used as a polar aprotic solvent in organic reactions. It is a urea derivative that has two 2,5-dimethoxyphenyl groups attached to the central urea nitrogen atom. DMPU is soluble in a wide range of organic solvents and is known for its high stability and low reactivity, making it a popular choice for reactions that require high solubility and low interference from the solvent. It is also used as a reagent and catalyst in various chemical reactions, including peptide coupling and synthesis of organic compounds. Additionally, DMPU has been studied for its potential as a novel electrolyte additive in high-performance lithium-ion batteries.
Check Digit Verification of cas no
The CAS Registry Mumber 1240-72-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1240-72:
(6*1)+(5*2)+(4*4)+(3*0)+(2*7)+(1*2)=48
48 % 10 = 8
So 1240-72-8 is a valid CAS Registry Number.

A simple and efficient synthesis of diaryl ureas with reduction of the intermediate isocyanate by triethylamine

Thirty symmetrical diaryl urea derivatives were synthesised in moderate to excellent yields from arylamine and triphosgene with triethylamine as a reducing agent for the intermediate, isocyanate. It was significant that part of the products could be collected in almost quantitative yield without column chromatography. The procedure under mild reaction conditions was tolerant of a wide range of functional groups. The structures of the compounds were determined by NMR, MS and X-ray crystallographic analyses.
