Product Overview
Pyrethrine 1 (CAS 121-21-1), with molecular formula C21H28O3 and molecular weight 328.20 g/mol. IUPAC: (2-methyl-4-oxo-3-penta-2,4-dienylcyclopent-2-en-1-yl) 2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropane-1-carboxylate.
Chemical Property Profile of Pyrethrine 1
Property Insights of Pyrethrine 1
The XLogP value of 5.4 indicates that Pyrethrine 1 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 43.4 Ų, Pyrethrine 1 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Pyrethrine 1 has 0 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
