dinor-12-oxo Phytodienoic Acid-d5 Exclusive Cayman Chemical Item Number 10696 Description dinor-12-oxo Phytodienoic acid-d5 (dinor-OPDA-d5) contains five deuterium atoms at the 4, 4′, 5, 5, and 5 positions. It is intended for use as an internal standard for the quantification of dinor-OPDA by GC- or LC-mass spectrometry (MS). In plants, certain unsaturated fatty acids are oxygenated and then further modified along the jasmonate pathway to produce plant hormones that are involved in senescence, flower development, mechanotransduction, and the response to herbivory.1↗ dinor-OPDA is an intermediate in the synthesis of jasmonic acid from hexadecatrienoic acid.2↗,3↗ dinor-OPDA can also be incorporated into glycerolipids and galactolipids, including certain arabidopsides.4↗,5↗ Synonyms dinor-OPDA-d5,dinor-12-oxo PDA-d5 Formal Name 4-oxo-5S-(2Z)-2-penten-4,4,5,5,5-d5-1-yl-2-cyclopentene-1S-hexanoic acid Molecular Formula C16H19D5O3 Formula Weight 269.4 Formulation A solution in methanol Purity ≥99% deuterated forms (d1-d5) λmax 220 nm Stability 1 year Storage -80°C Shipping Dry ice in continental US; may vary elsewhere SMILES O=C1[C@@H](C/C=CC([2H])([2H])C([2H])([2H])[2H])[C@@H](CCCCCC(O)=O)C=C1 InCHI Code 1S/C16H24O3/c1-2-3-5-9-14-13(11-12-15(14)17)8-6-4-7-10-16(18)19/h3,5,11-14H,2,4,6-10H2,1H3,(H,18,19)/b5-3-/t13-,14-/m0/s1/i1D3,2D2 InCHI Key SZVNKXCDJUBPQO-UBJGXVEQSA-N -80°C
