"(IR,2S)-N-Pyrrolidinyl norephedrine HCL" is a chemical compound that is a derivative of norephedrine. It is a sympathomimetic agent that acts as a central nervous system stimulant and a vasoconstrictor. It is commonly used as a nasal decongestant and a bronchodilator to relieve symptoms of congestion and respiratory issues. The chemical is typically administered in the form of a hydrochloride salt, which enhances its stability and solubility. It has been used in pharmaceutical formulations to treat conditions such as nasal congestion, asthma, and certain types of shock. However, it is important to use this chemical with caution and under the guidance of a healthcare professional, as misuse or overuse can lead to adverse effects such as increased heart rate, elevated blood pressure, and potential dependence.
Check Digit Verification of cas no
The CAS Registry Mumber 210558-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,5,5 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 210558-66:
(8*2)+(7*1)+(6*0)+(5*5)+(4*5)+(3*8)+(2*6)+(1*6)=110
110 % 10 = 0
So 210558-66-0 is a valid CAS Registry Number.

Paragraph 0159-0160; 0164, (2020/01/25)
The invention belongs to the technical field of chemical synthesis, and relates to a synthetic method of a chiral compound, in particular to a synthetic method of (1R, 2S)-1-phenyl-2-(pyrrolidine-1-yl) propan-1-ol. According to an ingenious synthesis strategy, asymmetric reduction can be realized during carbonyl reduction, and a target compound can be directly obtained at high yield. The problem that a target compound cannot be obtained at high yield through asymmetric reduction in the prior art is solved. Moreover, the synthesis of a high-purity compound (A) can be realized by using cheap hydrochloric acid and zinc chloride; in addition, no isomer is wasted; and according to the method, the use of norephedrine controlled product is avoided; the raw materials are cheap and easy to obtain,so that the synthesis cost is reduced; moreover, the preparation method disclosed by the invention is easy for industrial large-scale production.
