What are the physical and chemical properties of 4-{[4-Amino-6-(methoxymethyl)-5-(7-methoxy-5-methyl-1-benzothiophen-2-yl)pyrrolo[2,1-f][1,2,4]triazin-7-yl]methyl}-2-piperazinone (CAS: 1443530-05-9)?

4-{[4-Amino-6-(methoxymethyl)-5-(7-methoxy-5-methyl-1-benzothiophen-2-yl)pyrrolo[2,1-f][1,2,4]triazin-7-yl]methyl}-2-piperazinone (CAS: 1443530-05-9) is a crystalline solid with a molecular weight of approximately 687.74 g/mol. It has a low solubility in water but is soluble in organic solvents such as methanol and dimethylformamide. The compound is reactive towards base and can undergo hydrolysis under basic conditions. It is stable under normal storage conditions but should be stored in a cool, dry place away from direct sunlight.
