slightly yellow to brown crystalline powder

??

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].

?? ??

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

Purification Methods

It is soluble in hot H2O. UV (EtOH) has max 403nm (log 4.42) [Johnson J Am Chem Soc 75 2720 1953]. [Vandenbelt Anal Chem 26 726 1954.] The 2,4-dinitrophenylhydrazone has m 266-267o (from CHCl3 or EtOH) with 403nm (log 4.42), and the max semicarbazone has m 193-194o(dec)(from MeOH). The hydrochloride has m 98o(dec)(from H2O). [Beilstein 14 IV 100.]
