Description
NSC 240403, also known as N,N-Bis(2-chloroethyl)benzenesulfonamide, is a chemical compound that serves as a novel intermediate in the synthesis of Cetirizine (C281100). It is a significant component in the pharmaceutical industry due to its role in the production of Cetirizine, which is an antihistamine drug used to treat various allergic conditions.
Uses
Used in Pharmaceutical Industry:
NSC 240403 is used as a key intermediate in the synthesis of Cetirizine (C281100) for its antihistamine properties. NSC 240403 plays a crucial role in the development of medications that help alleviate symptoms of allergies, such as sneezing, itching, and runny nose, by blocking the effects of histamine in the body.
Check Digit Verification of cas no
The CAS Registry Mumber 58023-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,0,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58023-19:
(7*5)+(6*8)+(5*0)+(4*2)+(3*3)+(2*1)+(1*9)=111
111 % 10 = 1
So 58023-19-1 is a valid CAS Registry Number.

PROCESS FOR PREPARATION OF SUBSTANTIALLY OPTICALLY PURE LEVOROTATORY AND DEXTROROTATORY ENANTIOMERS OF CETIRIZINE USING NOVEL INTERMEDIATES
-
Page/Page column 2-3, (2009/12/04)
The present invention relates to a novel and commercially viable process for substantially optically pure levorotatory and dextrorotatory enantiomers of cetirizine intermediate, 1-[(4-chlorophenyl)phenylmethyl]piperazine, thereby producing substantially optically pure levorotatory and dextrorotatory enantiomers of cetirizine and their pharmaceutical acceptable acid addition salts thereof in high purity and in high yield using novel intermediates.
