Modified Chloronitroaniline

Updated: 2026-07-18

Overview

Dicloran, commonly referred to as Botran, is a chemical fungicide widely used in agriculture to combat fungal infections in crops. It is particularly effective against pathogens that cause post-harvest rot in fruits and vegetables. The compound was developed to address the need for reliable post-harvest treatments that extend the shelf life of produce. Dicloran is favored for its stability and low volatility, making it suitable for various storage and transportation conditions. Its formulation as a crystalline powder allows for easy application, either as a dust or in solution. The chemical is registered for use in many countries, though regulations may vary regarding its application rates and permissible residues.

Physical and Chemical Properties

Dicloran is a white to pale yellow crystalline solid with a molecular weight of 233.05 g/mol. It has a melting point of 192-194°C and a density of 1.5 g/cm³. The compound is slightly soluble in water but dissolves readily in organic solvents such as acetone and ethanol, which facilitates its formulation into various agricultural products. The chemical stability of Dicloran under normal storage conditions ensures a long shelf life, provided it is kept in a cool, dry environment. Its low volatility reduces the risk of airborne exposure during handling. These properties make it a practical choice for farmers and agribusinesses seeking effective and durable fungicidal solutions.

Main Applications

Dicloran is primarily used as a fungicide to control fungal diseases in crops, especially post-harvest. It is effective against pathogens like Botrytis cinerea and Sclerotinia spp., which cause significant losses in stored fruits and vegetables. Common applications include treatment of apples, pears, and citrus fruits to prevent rot during storage and transport. In addition to its agricultural uses, Dicloran is sometimes employed in non-crop settings, such as in the protection of ornamental plants and turf. Its broad-spectrum activity and residual effectiveness make it a versatile tool in integrated pest management programs. However, users must adhere to label instructions to avoid overuse and potential resistance development.

Safety and Storage

When handling Dicloran, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a respirator if dust is present. The compound can cause irritation upon contact with skin or eyes, and inhalation should be avoided. In case of exposure, rinse affected areas thoroughly with water and seek medical advice if symptoms persist. Storage of Dicloran requires a cool, dry place away from direct sunlight and moisture. Containers should be tightly sealed to prevent contamination and degradation. Proper disposal of unused product and empty containers must follow local environmental regulations to minimize ecological impact.

B2B Procurement Guide

For B2B buyers, sourcing Dicloran involves verifying the CAS number (99-30-9) and ensuring the product meets required purity standards. Suppliers should provide certificates of analysis and compliance with regional agricultural regulations. Bulk purchases may offer cost advantages, but buyers should assess storage capacity to maintain product integrity. Procurement professionals should also evaluate supplier reliability, delivery timelines, and after-sales support. Given the regulatory scrutiny of agricultural chemicals, it is advisable to work with vendors who can provide documentation for customs and usage compliance. Price negotiations should consider factors like volume discounts and shipping costs.
