8-Formyl-7-methoxycoumarin is a synthetic organic compound characterized by its chemical formula C10H8O4. It is a derivative of the naturally occurring coumarin molecule, featuring a formyl group (aldehyde) at the 8th position and a methoxy group (oxygen atom attached to a methyl group) at the 7th position. 8-Formyl-7-methoxycoumarin is often used as a fluorescent probe in biochemistry and molecular biology due to its ability to react with primary amines, forming a stable adduct that emits fluorescence upon excitation. This property makes it a valuable tool for detecting and quantifying amines in various biological samples. Additionally, 8-formyl-7-methoxycoumarin is employed in the development of chemiluminescent assays and as a reagent in the synthesis of other complex organic molecules.

6724-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6724-42-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,2 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6724-42:
(6*6)+(5*7)+(4*2)+(3*4)+(2*4)+(1*2)=101
101 % 10 = 1
So 6724-42-1 is a valid CAS Registry Number.

Geometrically Selective Denitrative Trifluoromethylthiolation of β-Nitrostyrenes with AgSCF3for (E)-Vinyl Trifluoromethyl Thioethers

Fang, Ge,Hong, Jianquan,Huang, Shuai,Jiang, Chao,Liu, Yang,Zhang, Wei,Zheng, Changge

, (2020/07/03)

An efficient copper(II)-promoted denitrative trifluoromethylthiolation under mild reaction conditions has been developed for vinyl trifluoromethyl thioethers to construct Cvinyl-SCF3 bonds with stable AgSCF3 as a source of the trifluoromethylthio. This reaction system tolerates a broad range of functional groups to commendably achieve a high product yield and excellent stereoselectivity of E/Z.

A route to the structure proposed for puetuberosanol and approaches to the natural products marshrin and phebalosin

Gillmore, Adam,Lauret, Christelle,Roberts, Stanley M.

, p. 4363 - 4375 (2007/10/03)

Synthesis of the structure claimed for puetuberosanol 1 (using the Juliá-Colonna oxidation in a key step) showed that the natural product was a different material. The isomeric epoxy alcohols 16-18 can be discounted from the alternatives. An analogue 19 of marshrin 2 was prepared but the synthesis of the natural product was thwarted by failure of a Juliá-Colonna oxidation in the key step. The epoxy ketone 29 was prepared by Darzens condensation and was converted into (±)-phebalosin 3.

Studies on Rutaceae: Part VI - Reacrtions and Rearrangements of Coumarins

Banerji, J.,Dhara, K. P.,Das, B.,Das, A. K.,Chatterjee, A.

, p. 21 - 25 (2007/10/02)

Interesting reactions and rearrangements of isoprenoid systems have been observed in naturally occuring compounds like 6-(3',4'-epoxy-3'-methyl-γ-butyrolactonyl)-7-methoxycoumarin (micromelumin) (1), 7-methoxy-8-(1',2'-epoxy-3'-methylbut-3'-enyl)coumarin (phebalosin) (2), 7-methoxy-8-(2'-hydroxy-3'-methylbut-3'-enyl)coumarin (auraptenol) (3) and 7-methoxy-8-(3'-methylbut-2'-enyl)coumarin (osthol) (4).These reactions/rearrangements have led to the synthesis of coumarins already isolated from nature.Micromelumin (1) with pyridinium chloride affords the naturally occuring angelical (5), 6-(3'-methyl-3'-chloro-4'-hydroxy-γ-butyrolactonyl)- 7-methoxycoumarin (6b), 7-methoxycoumarinyl-6-tetronic acid derivative (7) and 6-(1'-carboxy-2'-methyl-3',4'-dihydroxybutenyl)-7-methoxycoumarin (8).Phebalosin (2) has been used for the hemisynthesis of the two naturally occuring diastereoisomeric coumarins minumicrolin (9) and murrangatin (10).Osthol (4) and auraptenol (3) have been used for the synthesis of the naturally occuring arnottinin (14)

ACID REARRANGEMENTS OF THE MURRANGATINS

Wickramaratne, D. B. Mahinda,Kumar, Vijaya

, p. 6153 - 6156 (2007/10/02)

Acid-catalyzed rearrangements of threo- murrangatin gave coumarins with tetrahydrofuryl side-chains, differences in reactivity from the erythro- isomer being attributed to stereoelectronic control.
