87943-20-2 Usage
Potent and Selective Histamine H1 Receptor Antagonist
Methdilazine effectively blocks the histamine H1 receptors, reducing the impact of histamine in the body.
Antihistamine
Used for treating allergies, hay fever, and other allergic conditions by preventing histamine from causing allergy symptoms.
Allergy Symptoms
Methdilazine helps alleviate symptoms such as itching, sneezing, and watery eyes by blocking histamine's effects.
Sedative Effects
Methdilazine has calming properties, making it useful in the treatment of insomnia and other sleep disorders.
Drowsiness
As a side effect, methdilazine may cause drowsiness, which can impair alertness and make it dangerous to drive or operate heavy machinery.
Check Digit Verification of cas no
The CAS Registry Mumber 87943-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87943-20:
(7*8)+(6*7)+(5*9)+(4*4)+(3*3)+(2*2)+(1*0)=172
172 % 10 = 2
So 87943-20-2 is a valid CAS Registry Number.

N-[(4′-Substituted phenylthio)ethyl] phthalimide la-g and their corresponding n-propyl 2a-g, n-butyl 3a-g derivatives have been synthesised. The structure of these compounds were proved by UV, IR, 1H NMR, 13CMR and mass spectra. The 1H and 13C chemical shifts of the adjacent methylene protons and carbons of both the sulfur atom and phthalimido nitrogen group were reasonably correlated using σ° values. The carbon-nitrogen and the carbon-sulfur bond fissions in alkaline and acidic media were discussed.
