off-white to beige crystalline powder

The Uses of 4'-Chloroacetoacetanilide

4′-Chloroacetoacetanilide was used in recombinant androgen receptor competitive binding assay for analysis of natural, synthetic and environmental chemicals.

Definition

ChEBI: P-Chloroacetoacetanilide is an anilide.

General Description

4′-Chloroacetoacetanilide was trilithiated with lithium diisopropylamide and condensed with several aromatic esters, followed by neutralization, separate acid cyclization and rearrangements to yield 4-anilino-6-aryl-2H-pyran-2-ones. It undergoes three-component reaction with a mixture of aromatic aldehyde and 5-aminotetrazole to form N,7-diaryl-5-methyl-4,7-dihydrotetrazolo[1,5-a]pyrimidine-6-carboxamide.

Safety Profile

Moderately toxic by intraperitonealroute. Combustible whenexposed to heat or flame. Dangerous: see ANILINE andCYANIDE. Can react vigorously with oxidizing materials.To fight fire, use water, foam, CO2, water mist, drychemical. When heated to decompo
