WINTER - 236-2B PRE AND POSR =Y siudy #o681TBO398 February 5, 1962 COMMERCIAL CHEMICALS ANALYSIS OPL-314 (FC-143) FOR RIKER Reference: CCD Analytical Request #Is 16474, 16614, 17958 A white powdered solid labeled FC-143 Lot 37 (F-6052 Lot 94) (T-3141 coc) was received originally on October 28 and December 3, 1980 for characterization and analysis. This material was analyzed and used in several studies including the two year feeding study (T-G998COC) Riker Study #0281CROO12. The sample was re-analyzed for post o681 TB0398 study with s&nple received from D. Ricic@-2-9r Jan. 82. Sample was 100% solids. The sample analyzed as follows: GLC of Methyl Esters Pre Pbst C6 Acid C7 Acid C8 Acid (allisomers) Cg Acid Clo Acid Cx Acid 0.2 0.6 97.6 .8 .2 .5 .2 .4 98.4 .4 .2 .4 All values within experimentalland integration parameters.
