Usage

General Description

N,N''-methylenebis(urea) is a chemical compound often used in synthesis processes and as a slow-release fertilizer due to its nitrogen-releasing properties. It is known for being soluble in water and alcohol, and exists in solid form at room temperature. It is produced through a reaction process exerting gaseous formaldehyde with urea. The compound is categorized under urea formaldehyde condensates (UFC), which are derivatives of urea and formaldehyde. Its molecular formula is C3H8N4O2. Potential hazards may include harm to the eyes, skin or respiratory system, depending on the intensity and duration of exposure.

Synthesis and in vitro evaluation of N-Aryl pyrido-quinazolines derivatives as potent epidermal growth factor receptor inhibitors

A series of pyrido-quinazolines have been synthesised, characterized, and tested for their in vitro epidermal growth factor receptor (EGFR) tyrosine kinase inhibitory activity. The compounds were prepared from Alkylideno/arylideno-bis-ureas. Their final structure of the compounds was elucidated on the basis of spectral studies (IR, 1H NMR, FT-IR, and EI-MS). The cellular EGFR internalization response of selected compounds was evaluated using HeLa cells. Most of the synthesized compounds displayed potent EGFR-TK inhibitory activity and structurally halogenated derivatives had a pronounced effect in inhibiting EGFR internalization.

Synthesis, antibacterial and antifungal activity of some new pyrido quinazolones

Alkylideno/arylideno bis ureas 1 synthesized by ureido-alkylation in the presence of alcohols-which on treatment with p-aminobenzoic acid results in 4-aryl-6-carboxylato-1,2,3,4-tetrahydroquinazolines 2. Reaction of 2 with benzoin in presence of polyphosphoric acid yields 4-aryl-8,9-diphenyl-1,4 dihydro-3H, 7-oxo-1,3-diaza anthracene-2,6-dione 3. Condensation of 3 with aromatic primary amine affords N-aryl-8,9-diphenyl (-2-oxopyrido [g]-4-aryl-2-oxo-1,3-dihydro quinazolines 4. The new compound 4 has been screened for their antibacterial and antifungal activities.

Binding of phenols in the urea-formaldehyde-water system and the role of precondensation stage in the synthesis of polymethyleneurea

The precondensation stage (keeping of a solution of urea and formaldehyde in a neutral medium) in the synthesis of polymethyleneurea is examined experimentally and by mathematical simulation.
