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.
Observe the number of turns in an electromagnet's coil. A simple electromagnet can be made by wrapping a coil of wire around a nail and attaching its ends to a 1.5-volt battery, while commercial electromagnets have sizable cores of one of the magnet materials described above and large coils around them. You can also use the gaussmeter sensor to test the field strength at varying distances from the magnet. 2  Place the sensor at a series of defined distances from the magnet's pole and record the results. 3  This method would be suitable for teaching middle school and high school age students about magnetic fields.
