Propanamide, N-(4-methylphenyl)-N-[1-(2-phenylethyl)-4-piperidinyl]-, also known as 4-(4-methylphenyl)-N-[1-(2-phenylethyl)-4-piperidinyl]propanamide, is a complex organic compound with a molecular formula of C26H30N2O. It is a derivative of propanamide, featuring a 4-methylphenyl group and a 1-(2-phenylethyl)-4-piperidinyl group attached to the nitrogen atoms. Propanamide, N-(4-methylphenyl)-N-[1-(2-phenylethyl)-4-piperidinyl]- is characterized by its unique molecular structure, which includes a propionic acid backbone, a 4-methylphenyl ring, and a piperidine ring with a phenylethyl side chain. It is primarily used in the pharmaceutical industry as an intermediate in the synthesis of various drugs, particularly those targeting the central nervous system. Due to its complex structure, it is essential to handle Propanamide, N-(4-methylphenyl)-N-[1-(2-phenylethyl)-4-piperidinyl]- with care and follow proper safety protocols during its synthesis and use.

1838-67-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1838-67-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1838-67:
(6*1)+(5*8)+(4*3)+(3*8)+(2*6)+(1*7)=101
101 % 10 = 1
So 1838-67-1 is a valid CAS Registry Number.

Carbon-13 nuclear magnetic resonance spectra of fentanyl analogs

Brine,Boldt,Huang,Sawyer,Carroll

, p. 677 - 686 (2007/10/02)

Natural abundance carbon-13 chemical shifts are reported for the hydrochloride salts of fentanyl and fifteen analogs. The signals are assigned on the basis of chemical shift theory, SFORD multiplicities, signal intensities, comparisons with model compounds, and thiophene carbon-proton coupling constants. In addition to its forensic value, the data suggest that the solution conformations of the analogs are similar to that of fentanyl hydrochloride.
