| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Structure of 2',6'-dihydroxy-4,4'-dimethoxychalcone.[Pubmed:2088422]
Acta Crystallogr C. 1990 Sep 15;46 ( Pt 9):1712-5.
1-(2,6-Dihydroxy-4-methoxyphenyl)-3-(4-methoxyphenyl)-2-propen-1-o ne, C17H16O5, Mr = 300.31, orthorhombic, Pbca, a = 27.903 (3), b = 13.958 (2), c = 7.662 (1) A, V = 2984 (1) A3, Z = 8, D chi = 1.337 Mg m-3, lambda(Cu K alpha) = 1.5418 A, mu = 0.729 mm-1, F(000) = 1264, T = 295 K, R = 0.040 for 1702 observed reflections. Two intramolecular hydrogen bonds are observed. The hydroxyl H atom at O(6A) is hydrogen bonded to the C(9) carbonyl group with short distances O(6A)...O(9) = 2.406 (3) and O(9)...H(6A) = 1.38 (3), O(6A)--H(6A) = 1.09 (3) A, the angle O(6A)--H(6A)...O(9) is 153 (4) degrees. The other hydrogen bond is of the C--H...O type with distances C(8)...O(2A) = 2.778 (4), H(8)...O(2A) = 2.09 (3) A and the angle around H(8) is 124 (2) degrees. Conjugation is observed between the aromatic rings and the central enone system. The molecule is not planar, the angle between the planes of the phenyl rings being 13.1 (4) degrees. Intermolecular O--H...O bonds with distances O(6A)...O(2A) = 2.689 (2), H(2A)...O(6A) = 1.86 (4) A and angle O(2A)--H...O(6A) = 176 (4) degrees form endless chains of molecules along b.
