Basic Information：

Chemical Name: 1-[[[2,5 - dichloro - 4-(1,1,2,3,3,3 - hexafluoropropoxy)phenyl]amino]carbonyl]-2-(4 - chlorophenyl)hydrazine

CAS Number: 103055-07-8

Molecular Formula: C₂₁H₁₂Cl₃F₆N₃O₃

Molecular Weight: 581.69.

Mechanism of Action：

By inhibiting the activity of insect chitin synthase, it prevents the molting of insect larvae and pupation, leading to the death of pests. It has a preventive and control effect on external parasites of pets (such as cats and dogs) like fleas and ticks, and also has a certain effect on some internal parasites (such as the larval stages of roundworms and hookworms).

Main Uses：

Veterinary Field：

Used to prevent and control flea infections (adults and larvae) in pets such as cats and dogs. It can disrupt the flea life cycle and reduce the number of eggs and larvae in the environment.

It also has a killing effect on ticks (such as Ixodes scapularis), reducing the risk of tick - borne diseases (such as Lyme disease) transmission.

Agricultural field：

It was once used to control crop pests (such as lepidopteran larvae), but its application in agriculture is gradually decreasing. Now, more attention is focused on the veterinary drug field.

Formulations and Usage：

Common Dosage Forms: Oral tablets, topical drops, injections, etc.

Usage Examples:

Pet Deworming: Calculate the dosage according to the weight. Usually, administer the drug once a month and follow the veterinarian's instructions.

Precautions: Avoid mixing with other insecticides during the medication period. Use with caution in pregnant and lactating animals.

Safety and Adverse Reactions：

Safety: When used at the recommended dosage, it has a relatively high level of safety for pets. However, an overdose may cause gastrointestinal reactions (such as vomiting and diarrhea) or skin allergies.

Contraindicated Groups: Animals allergic to benzoylurea drugs are prohibited from use.

Environmental Impact: It is toxic to aquatic organisms, and care must be taken to avoid drug contamination of water sources.
