2,3-Dihydroxy-1,4-naphthoquinone, also known as juglone, is a naturally occurring organic compound with the chemical formula C10H6O4. It is a quinone derivative, characterized by its 1,4-naphthoquinone structure with two hydroxyl groups at the 2 and 3 positions. Juglone is a dark purple pigment found in the heartwood, leaves, and bark of the black walnut tree (Juglans nigra) and other plants in the Juglandaceae family. It has various applications, including its use as a natural dye, a chemical intermediate in the synthesis of other compounds, and a potential antimicrobial agent. However, it is also known for its phytotoxic properties, which can inhibit the growth of other plants when released into the soil.

605-37-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 605-37-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 605-37:
(5*6)+(4*0)+(3*5)+(2*3)+(1*7)=58
58 % 10 = 8
So 605-37-8 is a valid CAS Registry Number.

Enamino derivatives of 1,3-dioxoindane-2-carboxylic acid

Malamidou-Xenikaki, Elizabeth,Spyroudis, Spyros,Tsanakopoulou, Maria,Krautscheid, Harald

experimental part, p. 8392 - 8397 (2009/04/11)

(Chemical Equation Presented) Although 1,3-dioxoindane-2-carboxylic acid is highly unstable, its enamino derivatives can be isolated by careful hydrolysis of their esters with 2,4-dihydroxy-1,4-naphthoquinone. Crystal structure determination reveals the formation of two intramolecular hydrogen bonds, offering thus a possible explanation for the stability of these acids.

Dimethyldioxirane oxidation of hydroquinones into quinones and 2,3-dihydroxycyclohexene-1,4-diones

Adam,Schonberger

, p. 53 - 56 (2007/10/02)

Dehydrogenation of hydroquinones 1 by dimethyldioxirane affords quinones 2 and oxygen transfer the novel 2,3-dihydroxycyclohexene-1,4-diones 3; an electron transfer mechanism is proposed for these oxidations.
