1-Aminopropan-2-one oxime, also known as L-α-Acetohydroxamic acid or L-α-Acetohydroximic acid, is an organic compound with the chemical formula C3H7NO2. It is a derivative of propanone, featuring an amino group (-NH2) attached to the first carbon and an oxime group (-C(NOH)=) at the second carbon. 1-aminopropan-2-one oxime is a key intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is also used as a chiral building block in the preparation of enantiomerically pure compounds. 1-Aminopropan-2-one oxime is a white crystalline solid that is soluble in water and polar organic solvents. Its synthesis typically involves the reaction of acetone with hydroxylamine, followed by a reduction step to introduce the amino group. The compound is sensitive to hydrolysis and oxidation, requiring careful handling and storage conditions to maintain its stability.
The CAS Registry Mumber 2017-90-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,1 and 7 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2017-90: (6*2)+(5*0)+(4*1)+(3*7)+(2*9)+(1*0)=55 55 % 10 = 5 So 2017-90-5 is a valid CAS Registry Number.
