24221-86-1 Usage
Chemical Properties
white crystalline powder
Safety Profile
A poison by intraperitoneal, subcutaneous, and intravenous
routes. When heated to decomposition it
emits very toxic fumes of HCl and NOx. See
also EPHEDRINE
Purification Methods
Recrystallise the hydrochloride from EtOH/Et2O. The free base crystallises from *C6H6 with m 40-41o (Skita et al. Chem Ber 66 974 1933]. [Beilstein 13 H 254, 13 II 375, 13 III 1721, 13 IV 1879.]
Check Digit Verification of cas no
The CAS Registry Mumber 24221-86-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,2 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 24221-86:
(7*2)+(6*4)+(5*2)+(4*2)+(3*1)+(2*8)+(1*6)=81
81 % 10 = 1
So 24221-86-1 is a valid CAS Registry Number.
