(1RS,2SR)-2-amino-1-(4-hydroxy-3-methoxy-phenyl)-propan-1-ol, also known as (±)-synephrine, is a naturally occurring organic compound that belongs to the phenylethanolamine class. It is a chiral molecule with two chiral centers, resulting in four possible stereoisomers. This specific compound is a mixture of the 1R,2S and 1S,2R enantiomers, which are the naturally occurring forms. Synephrine is found in various plants, such as Citrus aurantium (bitter orange), and is known for its potential effects on metabolism and thermogenesis, although its efficacy and safety as a dietary supplement or pharmaceutical agent are subjects of ongoing research and debate. The compound's structure features a hydroxyl group at the 4-position and a methoxy group at the 3-position on the phenyl ring, which contribute to its biological activity.
The CAS Registry Mumber 16906-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,0 and 6 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 16906-84: (7*1)+(6*6)+(5*9)+(4*0)+(3*6)+(2*8)+(1*4)=126 126 % 10 = 6 So 16906-84-6 is a valid CAS Registry Number.
