Description:

DEET (N,N-Diethyl-meta-toluamide) is a broad-spectrum insect repellent used globally to repel mosquitoes, ticks, fleas, chiggers, and other biting insects. It is the active ingredient in many personal insect repellent formulations. DEET works by interfering with the insect's ability to detect humans through scent, thereby reducing bites and vector-borne disease risks.

• Appearance: Clear to pale yellow liquid

• Odor: Mild characteristic odor

• Boiling Point: 111–112°C at 1.6 mmHg

• Melting Point: −45°C

• Solubility: Slightly soluble in water; freely soluble in ethanol, acetone, and other organic solvents

• Stability: Stable under normal storage and usage conditions. Avoid exposure to strong oxidizing agents and direct sunlight.

Specification Parameters:

• Purity (GC): ≥99.0%

• Moisture Content: ≤0.3%

• Acidity (as HCl): ≤0.1%

• Color (APHA): ≤100

• Refractive Index (n20D): 1.521–1.531

Applications:

DEET is used in insect repellent sprays, lotions, wipes, and wearable devices to prevent bites from disease-carrying insects such as mosquitoes (including malaria, dengue, and Zika vectors) and ticks (Lyme disease). It is suitable for use on skin, clothing, and outdoor gear.
