Product Overview
GB-1a (CAS 19456-83-8), with molecular formula C30H22O10 and molecular weight 542.12 g/mol. IUPAC: (2S)-8-[(2S,3R)-5,7-dihydroxy-2-(4-hydroxyphenyl)-4-oxo-2,3-dihydrochromen-3-yl]-5,7-dihydroxy-2-(4-hydroxyphenyl)-2,3-dihydrochromen-4-one.
Chemical Property Profile of GB-1a
Property Insights of GB-1a
The XLogP value of 4.6 indicates that GB-1a is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 174.0 Ų indicates high polarity, suggesting GB-1a may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, GB-1a has 6 hydrogen bond donor(s) and 10 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
