CAS 76769-07-8 is 2- [2-chloro-4- (trifluoromethyl) aniline] -3-methylbutyric acid, which is a key synthetic intermediate of the pyrethroid insecticide Tau fluvalinate. Its chemical formula is C ₁ ₂ H ₁ ∝ ClF ∝ NO ₂, and its molecular weight is approximately 295.69.

Basic Information
-Chinese name: 2- [2-chloro-4- (trifluoromethyl) aniline] -3-methylbutyric acid
-English name: (2S) -2- {[2-chloro-4- (trifluoromethyl) phenyl] amino} -3-methylbutanoic acid
-Molecular formula: C ₁₂ H ₁∝ ClF ∝ NO ₂
-Molecular weight: 295.69
-Appearance: White to pale yellow solid
-Melting point: 63-65 ° C
-Boiling point: approximately 381.5 ° C (760 mmHg)
-LogP: Approximately 3.56 (with strong fat solubility)
-Solubility: Insoluble in water, slightly soluble in organic solvents such as methanol and chloroform

Main purpose and status
-Core application: As an important precursor intermediate for fenpropathrin, it is used for pesticide synthesis; Some materials are also labeled as “Impurity 2 of Fluazuron”.
-Application areas: Mainly used for industrial production of pyrethroid insecticides and related pharmaceutical/agrochemical research and development.
-Structural features: Contains chiral centers (usually in the S configuration) and trifluoromethyl groups, which have a significant impact on the biological activity of subsequent products.

Precautions
-The substance itself is not the final insecticide product, but a synthetic intermediate; Its downstream product, cyhalothrin (CAS 102851-06-9), is a highly effective broad-spectrum acaricide insecticide.
-It is recommended to store in a cool and dry place (2-8 ° C is recommended for some materials) and avoid direct sunlight.
