Urea, N-(1-methylethyl)-N'-(5-methyl-3-isoxazolyl)
1. Basic Product Information
Product Name: Urea, N-(1-methylethyl)-N'-(5-methyl-3-isoxazolyl)
CAS Number: 55807-61-9
Molecular Formula: C8H13N3O2
Molecular Weight: 183.21
Synonyms: 1-isopropyl-3-(5-methylisoxazol-3-yl)urea, Isopropyl methylisoxazolyl urea
Product Category: Heterocyclic substituted urea fine chemical, pesticide intermediate, biocidal raw material, organic synthesis substrate
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white crystalline powder
- Odor: Faint mild heterocyclic odor
- Solubility: Soluble in ethanol, methanol, chloroform, DMSO; slightly soluble in hot water; insoluble in cold water and aliphatic mineral oil
- Melting Point: 148–152 °C
- Density (20 °C): 1.19 g/cm3
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Stable under neutral and weak acidic aqueous systems; urea hydrolysis occurs under strong alkaline heating to generate isopropylamine and 5-methyl-3-aminoisoxazole
Chemical Characteristics
- Molecular Structure: Disubstituted urea heterocyclic compound, one N linked with isopropyl group, another N connected to 5-methylisoxazol-3-yl ring
- Core Functional Mechanism: Multi-nitrogen functional molecule with active urea bond; used for cyclization synthesis of guanidine, isoxazole pesticide derivatives; bacteriostatic skeleton for industrial biocide synthesis
- Photostability: Mildly light-sensitive; long-term UV irradiation causes slight yellow discoloration
- Thermal Stability: Stable below 110 °C; heating above 140 °C triggers urea bond cleavage and decomposition
- Chemical Compatibility: Compatible with polar organic solvents and neutral resin raw materials; incompatible with strong oxidants, concentrated strong alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Pesticide Synthetic Intermediate
Key starting material for manufacturing isoxazole urea herbicides, fungicides and plant growth regulators - Industrial Biocide Raw Material
Synthetic precursor for water treatment bactericide, textile anti-mold finishing auxiliary - Fine Chemical Synthetic Raw Material
Substrate for manufacturing guanidine salt, nitrogen-containing corrosion inhibitor and cationic flocculant intermediates - Laboratory Biochemical Reagent
Heterocyclic urea substrate for amidase enzyme activity research and organic cyclization reaction study
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pesticide Fine Chemicals
Reason: Isopropyl isoxazolyl substituted urea industrial intermediate for pesticide and environmental protection chemical synthesis
2) English Product Group Dropdown Options
