3,4-dihydroxyphenylacetone Chemical Properties,Uses,Production

Description

3'',4''-Dihydroxyphenylacetone (Item No. 19522) is an analytical reference standard. It is a minor metabolite of 3,4-MDEA (Item Nos. 14085 | 15689), MDMA, and α-methyldopa produced by oxidative deamination. This product is intended for forensic and research applications.

Description

3',4'-Dihydroxypropiophenone, also known as DOPA, is a metabolite of dopamine, which is produced in the brain and kidneys. DOPA is a precursor to the synthesis of melanin, which is found in skin cells. Glutamate dehydrogenase converts DOPA to 3-methoxytyramine, which can be detected chromatographically in urine samples. Examining a urine sample for DOPA testing can be used to diagnose Parkinson's disease. DOPA may also be detected in plasma in patients with bacterial and urinary tract infections

Chemical Properties

Thick Yellow Oil

Uses

3',4'-Dihydroxyphenylacetone , MDMA, and α-methyldopa produced by oxidative deamination. This product is intended for forensic and research applications.

Uses

A metabolite of racemic 3,4-methylenedioxyethylamphetamine.

Production Methods

3,4-dihydroxylphenylacetaldehyde (DHPAA) synthase catalyzes a complicated decarboxylation-deamination process of α-methyl dopa (AMD), leading to the production of 3,4-dihydroxyphenylacetone.
3,4-dihydroxyphenylacetone

Definition

ChEBI: 3,4-Dihydroxyphenylacetone is an alkylbenzene.
