1570-12-3

7-O-benzyl-3,4′-di-O-methylkaempferol is a naturally occurring flavonoid compound, characterized by its unique chemical structure. 7-O-benzyl-3,4′-di-O-methylkaempferol is derived from kaempferol, a flavonoid found in various plants, and is modified with a benzyl group at the 7-O position and two methyl groups at the 3 and 4′ positions. The presence of these functional groups contributes to its distinct chemical properties and potential biological activities. Research on such flavonoids often focuses on their antioxidant, anti-inflammatory, and potential anticancer effects, although the specific properties and applications of 7-O-benzyl-3,4′-di-O-methylkaempferol would require further investigation.

1570-12-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1570-12-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1570-12:
(6*1)+(5*5)+(4*7)+(3*0)+(2*1)+(1*2)=63
63 % 10 = 3
So 1570-12-3 is a valid CAS Registry Number.

Selective methylation of kaempferol via benzylation and deacetylation of kaempferol acetates

Mei, Qinggang,Wang, Chun,Yuan, Weicheng,Zhang, Guolin

, p. 288 - 293 (2015)

A strategy for selective mono-, di- and tri-O-methylation of kaempferol, predominantly on the basis of selective benzylation and controllable deacetylation of kaempferol acetates, was developed. From the selective deacetylation and benzylation of kaempferol tetraacetate (1), 3,4′,5,-tri-O-acetylkaempferol (2) and 7-O-benzyl-3,4′5,-tri-O-acetylkaempferol (8) were obtained, respectively. By controllable deacetylation and followed selective or direct methylation of these two intermediates, eight O-methylated kaempferols were prepared with 51-77% total yields from kaempferol.
