Internal Correspondence 5| I tI i rI i V; To From: Subject: Date: D. R. RICKER - 53-4N COMMERCIAL CHEMICALS ANALYTICAL REPORT #308 L. D. WINTER - 236-2B PRE AND POST STUDY ANALYSIS OF STUDY #068lTB0398 (PC-143) FOR RIKER February 5, 1985 Reference: CCD Analytical Request # 's 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 #028lCR0012. The sample was re-analyzed for post 0681 TB0398 study with sample received from D. Ricker 29 Jan. 82. Sample was 100% solids. The sample analyzed as follows: GLC of Methyl Esters Pre Post Cg Acid C7 Acid Cg Acid (all isomers) Cg Acid C]_o Acid Cx Acid 0.2 0.6 97.6 .8 .2 .5 .2 .4 98.4 .4 .2 .4 All values within experimental and integration parameters Elemental Analysis: Element Theo: Pre Post F C N H 0 by diff. 66.13 22.27 3.24 0.92 7.42 0 66.2 22.2 3.5 0.7 7.4 68 ppm 65-9 22.2 3.6 0.7 7-6 68 ppm MW = 431 003111 2- - Spectroscopic Infrared spectra #16474-1 and 17958-1 are identical and match reference spectra. NMR spectra H 8386, F 8388-9 (Pre) and F 10163-4 (Post) are identical and match reference spectra. The chain is 79% straight chain. 9% (CFgJ^F" branching ana 12% Lack bone branched. Conclusions FC-143 Lot 37 has an analysis within specifications, is stable and is representative of conmerclal material. LCW/hc U '-z - dc: M. T. Case - 218-2 E. Gartner - 218-2 E. G.
