Product Overview
previtamin D2 (CAS 21307-05-1), with molecular formula C28H44O and molecular weight 396.34 g/mol. IUPAC: (1S)-3-[(Z)-2-[(1R,3aR,7aR)-1-[(E,2R,5R)-5,6-dimethylhept-3-en-2-yl]-7a-methyl-1,2,3,3a,6,7-hexahydroinden-4-yl]ethenyl]-4-methylcyclohex-3-en-1-ol.
Chemical Property Profile of previtamin D2
Property Insights of previtamin D2
The XLogP value of 7.641 indicates that previtamin D2 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 20.23 Ų, previtamin D2 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, previtamin D2 has 1 hydrogen bond donor(s) and 1 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
