18810-21-4 Usage
Description
(+)-Isoproterenol hydrochloride, also known as isoprenaline, is a synthetic catecholamine and a non-selective beta adrenergic agonist. It possesses bronchodilating, positive inotropic, and chronotropic properties, making it a versatile medication for respiratory and cardiac conditions.
Uses
Used in Respiratory Medicine:
(+)-Isoproterenol hydrochloride is used as a bronchodilator for the treatment of asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the smooth muscles in the airways, facilitating easier breathing.
Used in Cardiology:
(+)-Isoproterenol hydrochloride is used as a medication for the treatment of bradycardia and heart block. Its positive inotropic and chronotropic effects increase the force and rate of heart contractions, improving cardiac function.
However, due to its non-selective nature, (+)-Isoproterenol hydrochloride can also cause adverse effects such as increased heart rate and blood pressure, tremors, and anxiety. Therefore, its use must be carefully monitored to ensure patient safety and optimal therapeutic outcomes.
Check Digit Verification of cas no
The CAS Registry Mumber 18810-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,1 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18810-21:
(7*1)+(6*8)+(5*8)+(4*1)+(3*0)+(2*2)+(1*1)=104
104 % 10 = 4
So 18810-21-4 is a valid CAS Registry Number.

-
Paragraph 0018; 0020; 0021; 0023; 0024; 0026, (2017/08/31)
The invention relates to a method for preparing isoproterenol hydrochloride. The method comprises the following steps: (1) preparation of 2-amino-1-(3, 4-dihydroxy phenyl)-ethanone; (2) preparation of isoproterenol ketone hydrochloride; and (3) preparation of isoproterenol hydrochloride. The method disclosed by the invention adopts a reaction system of glycine and zinc chloride instead of a reaction system of monochloro acetic acid and phosphorus oxychloride, so that the method has the advantages that the environmental protection cost is reduced; the reaction yield is increased; the industrial production is benefited; the reaction condition is mild; the catalyst quantity is little; and the process is simple. Compared with conventional synthetic processes, the method disclosed by the invention has obvious economic benefit and environmental benefit.
