Procaterol, applied as procaterol hydrochloride (USAN), is an intermediate-acting Î²2-adrenergic receptor agonist used for the treatment of asthma.It has never been filed for FDA evaluation in the United States, where it is not marketed.The drug is readily oxidised in the presence of moisture and air, making it unsuitable for therapeutic use by inhalation.Pharmaceutical company Parke-Davis / Warner-Lambert researched a stabilizer to prevent oxidation, but an effective one was never developed.he drug is readily oxidised in the presence of moisture and air, making it unsuitable for therapeutic use by inhalation.

Lassaigneâs test is used to detect the presence of elements: Nitrogen (N), Sulfur (S), Chlorine (Cl), Bromine (Br) and Iodine (I). This test involves following two steps. i) preparation of sodium fusion extract (SFE). ii) Detection of elements using SFE.
Ferrimagnetism is exhibited by ferrites and magnetic garnets. The oldest known magnetic substance, magnetite (iron(II,III) oxide; Fe 3 O 4), is a ferrimagnet; it was originally classified as a ferromagnet before Neel 'nÃ©el s discovery of ferrimagnetism and antiferromagnetism in. 1948errimagnetism can also occur in molecular magnets. A classic example is a dodecanuclear manganese molecule with an effective spin of S = 10 derived from antiferromagnetic interaction on Mn(IV) metal centres with Mn(III) and Mn(II) metal centres.
