What are the physical and chemical properties of (4aR,6aR,6aS,6bR,8aR,9R,10S,12aR,14bS)-10-[(2S,4S,5S)-3-[(2S,3R,4R,5S,6S)-3,5-dihydroxy-6-methyl-4-[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxyoxan-2-yl]oxy-4,5-dihydroxyoxan-2-yl]oxy-9-(hydroxymethyl)-2,2,6a,6b,9,12a-hexamethyl-1,3,4,5,6,6a,7,8,8a,10,11,12,13,14b-tetradecahydropicene-4a-carboxylic acid (CAS: 128730-82-5)?

This compound is a complex organic acid with a molecular weight of approximately 1000 g/mol. It crystallizes in the form of a solid with a melting point between 150-160°C. It is poorly soluble in water but soluble in organic solvents such as ethanol and methanol. Chemically, it is highly reactive due to the presence of multiple functional groups including hydroxyl and carboxylic acid groups. It has a pKa of around 2.5-3.5, indicating strong acidity.
