Description
Pipradrol, a synthetic piperidine derivative, is a psychoactive drug that acts as a stimulant and anorexiant. It is structurally related to pipradrol and has been used for its potential cognitive-enhancing and appetite-suppressing properties.
Uses
Used in Pharmaceutical Industry:
Pipradrol is used as a cognitive enhancer for its potential to improve memory, attention, and learning capabilities. It is believed to modulate neurotransmitter systems, such as dopamine and norepinephrine, leading to enhanced cognitive performance.
Used in Weight Management:
Pipradrol is used as an appetite suppressant to help individuals manage their weight by reducing food intake. Its anorexiant properties are thought to be due to its action on the central nervous system, which can help control hunger and promote a feeling of satiety.
Used in Treatment of Narcolepsy:
Pipradrol has been used as a treatment for narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden episodes of muscle weakness. Its stimulant effects can help improve wakefulness and reduce the frequency of sleep attacks.

Manufacturing Process
A mixture of 48 g (0.167 mole) of α,α-diphenyl-2-pyridinemethanol hydrochloride (Emraert et al., Ber. 72B, 1188 (1939); 74B, 714 (1940), 160 ml of ethanol, and 3 0.5 g of Adams' platinum catalyst was shaken under an initial hydrogen pressure of 60 pounds. The theoretical amount of hydrogen was absorbed in 5 hours. The reaction mixture was refluxed, diluted with enough water to dissolve all the white solid, and filtered hot from the catalyst. The filtrate was cooled and filtered; yield of 38 g of α,α-diphenyl-alpha-(2piperidyl)methanol white product melting at 308-309°C with decomposition.A mixture of 3.5 grams (0.013 mole) of the above α,α-diphenyl-alpha-(2piperidyl)methanol, 4 g (0.05 mole) of formaldehyde (37%), and 6 grams (0.1 mole) of formic acid was refluxed for 2 days. The reaction mixture was treated with 1.3 g (0.013 mole) of conc. hydrochloric acid and vacuum distilled on the steam bath. The residue was recrystallized from butanone to give the α,αdiphenyl-alpha-(2-piperidyl)methanol hydrochloride which melted at 228229°C (dec.).
Therapeutic Function
Central stimulant
World Health Organization (WHO)
Pipradrol, a central nervous system stimulant, was introduced in
1955 for use as an anorexic agent. Pipradrol is controlled under Schedule IV of the
1971 Convention on Psychotropic Substances.

Check Digit Verification of cas no
The CAS Registry Mumber 467-60-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 467-60:
(5*4)+(4*6)+(3*7)+(2*6)+(1*0)=77
77 % 10 = 7
So 467-60-7 is a valid CAS Registry Number.

A simple iridicycle catalyst for efficient transfer hydrogenation of n-heterocycles in water
Talwar, Dinesh,Li, Ho Yin,Durham, Emma,Xiao, Jianliang
supporting information, p. 5370 - 5379 (2015/03/30)
A cyclometalated iridium complex is shown to catalyse the transfer hydrogenation of various nitrogen heterocycles, including but not limited to quinolines, isoquinolines, indoles and pyridinium salts, in an aqueous solution of HCO2H/HCO2Na under mild conditions. The catalyst shows excellent functional-group compatibility and high turnover number (up to 7500), with catalyst loadings as low as 0.01 mol % being feasible. Mechanistic investigation of the quinoline reduction suggests that the transfer hydrogenation proceeds via both 1,2- and 1,4-addition pathways, with the catalytic turnover being limited by the step of hydride transfer. An easily accessible iridicycle catalyst effects the transfer hydrogenation of a wide variety of N-heterocycles in water, including quinolines, isoquinolines, indoles, quinoxalines, and pyridines. The catalyst shows excellent functional-group compatibility and high turnover number (up to 7500), even with low catalyst loadings.
