1213240-07-3 Usage
Uses
Used in Pharmaceutical Industry:
3-Azetidinecarboxylic acid, 3-methyl-, is used as a reagent for the synthesis of PD-1/PD-L1 inhibitors, which are crucial in the treatment of various types of cancer. These inhibitors play a significant role in modulating the immune system's response to cancer cells, thereby enhancing the body's ability to fight the disease.
In the synthesis of PD-1/PD-L1 inhibitors, 3-Azetidinecarboxylic acid, 3-methyl-, serves as a key building block that contributes to the development of novel and effective cancer therapeutics. Its unique structure and reactivity make it a valuable component in the design and synthesis of these inhibitors, which can potentially lead to improved treatment options for patients suffering from cancer.
Check Digit Verification of cas no
The CAS Registry Mumber 1213240-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,2,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1213240-07:
(9*1)+(8*2)+(7*1)+(6*3)+(5*2)+(4*4)+(3*0)+(2*0)+(1*7)=83
83 % 10 = 3
So 1213240-07-3 is a valid CAS Registry Number.

A novel rearrangement reaction conversion of 3-(chloromethyl)azetidin-2-ones to azetidine-3-carboxylic acid esters
Bartholomew,Stocks
, p. 4795 - 4798 (2007/10/02)
Transformation of 3-(chloromethyl)azetidin-2-ones to azetidine-3-carboxylic acid esters is described. The readily available 3-(chloromethyl)azetidin-2-ones rearranged in good yields to azetidine-3-carboxylic acid esters on treatment with alkoxides. An alternative ring opening - ring closure procedure is also identified.
