19212-42-1

1-(5-METHYL-3-PHENYLISOXAZOL-4-YL)ETHAN-1-ONE, commonly known as MPAI, is a synthetic compound that exhibits psychoactive properties. It is a member of the cathinone class, which are structurally and functionally similar to amphetamines, and possesses stimulant effects. MPAI functions as a reuptake inhibitor for both dopamine and norepinephrine, thereby increasing the levels of these neurotransmitters in the brain. This action can lead to a range of effects, including euphoria, heightened energy, and improved alertness. However, the use of MPAI is not without risks, as it may cause cardiovascular and mental health issues. Due to these potential dangers, MPAI is often regulated as a controlled substance and is banned in many regions.

19212-42-1 Usage

Uses

Used in Pharmaceutical Research:
MPAI is utilized as a research chemical for studying the effects of dopamine and norepinephrine reuptake inhibition on the brain. Its psychoactive properties make it a valuable tool in understanding the mechanisms of action for stimulant drugs and their potential therapeutic applications.
Used in Controlled Substances Regulation:
Due to its psychoactive effects and potential for abuse, MPAI is used as a reference compound in the development and enforcement of controlled substance regulations. This helps in identifying and monitoring the circulation of similar substances in the market to prevent misuse and ensure public safety.

Check Digit Verification of cas no

The CAS Registry Mumber 19212-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,1 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19212-42:
(7*1)+(6*9)+(5*2)+(4*1)+(3*2)+(2*4)+(1*2)=91
91 % 10 = 1
So 19212-42-1 is a valid CAS Registry Number.

Hypervalent Iodine(III) Reagent Mediated Regioselective Cycloaddition of Aldoximes with Enaminones

Yoshimura, Akira,Jarvi, Melissa E.,Shea, Michael T.,Makitalo, Cody L.,Rohde, Gregory T.,Yusubov, Mekhman S.,Saito, Akio,Zhdankin, Viktor V.

, p. 6682 - 6689 (2019/11/02)

An efficient oxidative cycloaddition of enaminones with nitrile oxides generated in situ from respective aldoximes using hypervalent iodine reagents has been developed. Reactions of various aldoximes with enaminones in the presence of [hydroxy(tosyloxy)iodo]benzene involved the regioselective cycloaddition reaction resulting in the formation of the 3,4-disubstituted isoxazoles in moderate to good yields. Structures of several isoxazole products were confirmed by a single X-ray crystallography.
