69539-48-6 Usage
General Description
2-Azetidinecarboxylic acid, hydrochloride is a chemical compound that is used as an intermediate in the synthesis of pharmaceuticals and other organic compounds. It is a crystalline white solid that is soluble in water. 2-AZETIDINECARBOXYLIC ACID, HYDROCHLORIDE is a derivative of azetidine, which is a four-membered ring with a nitrogen atom. The hydrochloride salt form of 2-azetidinecarboxylic acid is often used because it has better solubility and stability than the free base form. 2-AZETIDINECARBOXYLIC ACID, HYDROCHLORIDE is commonly used in the pharmaceutical industry as a building block for the synthesis of drugs and other bioactive compounds. It is also used in academic research for chemical synthesis and organic chemistry studies.
Check Digit Verification of cas no
The CAS Registry Mumber 69539-48-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,3 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69539-48:
(7*6)+(6*9)+(5*5)+(4*3)+(3*9)+(2*4)+(1*8)=176
176 % 10 = 6
So 69539-48-6 is a valid CAS Registry Number.

Methods for producing N-protected-azetidine-2-carboxylic acids
-
, (2008/06/13)
There is disclosed a method for producing an essentially enantiomerically pure N-protected-azetidine-2-carboxylic acid of formula (1): which method is characterized by: subjecting a crude enantiomerically excess N-protected-azetidine-2-carboxylic acid comprising said enantiomer represented by formula (1) in excess to the other enantiomer thereof to crystallization in an organic solvent selected from aromatic hydrocarbon, aliphatic ether, aliphatic alcohol, aliphatic ketone, aliphatic nitrile, aliphatic amide, aliphatic sulfoxide, aliphatic ester and a mixed solvent thereof, wherein R is: an optionally substituted alkyl, alicyclic or alicyclicalkyl group, an optionally substituted alkenyl group, an optionally substituted aryl group, an optionally substituted heteroaryl group, or a dialkylamino group, and absolute configuration of the asterisked asymmetric carbon atom is S or R.
