Description
4-Aminoacetophenone is in the form of yellow needle-like crystals, with a melting point of 106°C, a boiling point of 293-295°C, and 195-200°C (2kPa). Soluble in hot water, soluble in alcohol, ether, dilute hydrochloric acid and dilute sulfuric acid, it is slightly soluble in benzene and cold water. Has a special pleasant fragrance. It can be used as a pharmaceutical intermediate.
Applications
4′-Aminoacetophenone, is used in pharmaceuticals, medicines and other organic products. It is also used as a reagent for the photometric determination of Ce. As pharmaceutical intemediate or in the determination of palladium and vitaminB1.
Synthesis
Through a Williamson ether synthesis method and Smiles rearrangement reaction, benzamide compounds are produced, then the 4-aminoacetophenone preparation is finished after hydrolysis.

Chemical Properties
slightly yellow to brown crystalline powder
Uses
4'-Aminoacetophenone, is used in pharmaceuticals, medicines and other organic products. It is also used as a reagent for the photometric determination of Ce. As pharmaceutical intemediate or in the determination of palladium and vitaminB1.
Uses
4-Aminoacetophenone is a novel utilization of aminophenone derivative in toxicology used for treating intoxications with cyanogenic toxic substances.
Uses
4-Aminoacetophenone can be used as an organic reagent to synthesize a variety of organic substances, which is used in the field of anticancer drug preparation and analytical detection. Using it as a raw material, Schiff alkali palladium(II) complexes (cyclopalladiumated compounds) are synthesized by combining metals with carbon atoms. The drug inhibits and kills invasive melanoma cancer cell line (MDA-MB-435)[1]. Hydroxylamine hydrochloride and 4-aminoacetophenone synthesize 4-aminoacetophenone oxime (APO) by oximation reaction, which has a high sensitivity to Organophosphorus (OP）nerve agent mimic-diethylcyanophosphonate. APO can be used to prepare electrochemical sensors with high sensitivity and selectivity to detect OPs[2].
General Description
4′-Aminoacetophenone, commonly known as Clenbuterol Impurity D, is a related compound of sympathomimetic amine drug clenbuterol. Clenbuterol belongs to a group of compounds referred to as β-2-agonists and is generally used in the treatment of asthma.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Safety Profile
Poison by ingestion and intraperitoneal routes. When heated to decomposition it emits toxic fumes of NO,. See also AROMATIC AMINES
