IUPAC: (3R,4S,5S,6R,7R,9R,11R,12R,13S,14R)-6-[(2S,3R,4S,6R)-4-(dimethylamino)-3-hydroxy-6-methyloxan-2-yl]oxy-14-ethyl-7,12,13-trihydroxy-4-[(2R,4R,5S,6S)-5-hydroxy-4-methoxy-4,6-dimethyloxan-2-yl]oxy-3,5,7,9,11,13-hexamethyl-oxacyclotetradecane-2,10-dione;octadecanoic acid.
Chemical Property Profile of Erythromycin Stearate
Property Insights of Erythromycin Stearate
The XLogP value of 8.12 indicates that Erythromycin Stearate is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 231.0 Ų indicates high polarity, suggesting Erythromycin Stearate may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Erythromycin Stearate has 6 hydrogen bond donor(s) and 16 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
