35364-15-9 Usage
Uses
1-(2-Amino-5-hydroxyphenyl)propan-1-one is a useful synthetic intermediate. It is used in the asymmetrical synthesis of (S)-4-ethyl-6,7,8,10- tetrahydro-4-hydroxy-1H-pyrano[3,4-f]indolizine-3,6,10(4H)-trione, a key intermediate for synthesis of irinotecan and other camptothecin analogs. It is also used in the synthesis of E-?ring-?modified (RS)?-?camptothecin analogs as antitumor agents.
Preparation
Obtained by UV-irradiation of 3-ethyl-2,1-benzisoxazole in 66% sulfuric acid for 90 min at 80–90° Also prepared from 2-nitro-5-hydroxybenzaldehyde (five steps) or from p-anisidine.
Check Digit Verification of cas no
The CAS Registry Mumber 35364-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,3,6 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 35364-15:
(7*3)+(6*5)+(5*3)+(4*6)+(3*4)+(2*1)+(1*5)=109
109 % 10 = 9
So 35364-15-9 is a valid CAS Registry Number.
