Rac N-Acetyl Ephedrine, also known as N-Acetyl-α-methylphenethylamine, is a chemical compound derived from ephedrine, a natural alkaloid found in plants like Ephedra. It is a chiral molecule, meaning it has a non-superimposable mirror image, and is commonly used as a precursor in the synthesis of various pharmaceuticals, including decongestants and stimulants. Rac N-Acetyl Ephedrine is a white crystalline powder that is soluble in water and has a melting point of around 68-70°C. Due to its potential use in the illicit production of methamphetamine, it is regulated in many countries, and its sale and distribution are subject to strict controls.

5661-42-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5661-42-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,6 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5661-42:
(6*5)+(5*6)+(4*6)+(3*1)+(2*4)+(1*2)=97
97 % 10 = 7
So 5661-42-7 is a valid CAS Registry Number.

MISE EN EVIDENCE PAR RMN-(1)H ET -(13)C D'ISOMERISME Z/E ET D'EQUILIBRE CONFORMATIONNEL SUR UNE SERIE DE DERIVES MONO- ET DIACETYLES DE 2-ALKYLAMINO-1-PHENYLPROPAN-1-OLS

Tytgat, D.,Gelbcke, M.

, p. 479 - 490 (2007/10/02)

(1)H- and (13)C NMR studies of mono- and diacetylated-erythro- and threo-2-alkylamino-1-phenylpropan-1-ols, C6H5CHOHCHNHRCH3 (R = H, CH3, C2H5 AND i-C3H7) show that the series exhibit Z/E isomerism about the C-N amide bond.The Z/E ratio increases in the monoacetylated series CH3 1-C2 and N-C2 bonds.In the Z configuration, the conformer Z-s-syn where the proton H-2 is syn with the N-alkyl substituent predominates.
