| 2,2,3,3,4,4,5,5-Octachlorobiphenyl is a toxic persistent organic pollutant. Synonyms: PCB194, 1,1-Biphenyl, 2,2,3,3,4,4,5,5-octachloro-, 2,2,3,3,4,4,5,5-Octachloro-1,1-biphenyl, 2,2,3,3,4,4,5,5-Octachlorobiphenyl, 2,3,4,5,2,3,4,5-Octachlorobiphenyl, CB 194, PCB 194, 2,2,3,3,4,4,5,5-OctaCB, 1,2,3,4-tetrachloro-5-(2,3,4,5-tetrachlorophenyl)benzene CAS No: 35694-08-7 Molecular Formula: C12H2Cl8 Molecular Weight: 429.77 Appearance: Neat Purity: 99% Method of Identification: NMR, RT, IR, MS Solubility: Water Water (KF): 0.1% Instructions for Use: It is recommended to use 1mg as the minimum sample size and if less material is used, to increase the certified uncertainty by a factor of two for half sample and four for a quarter of sample. If storage after opening is necessary, the RM should be tightly closed and kept from light and moisture. If the RM was in a sealed ampoule, it should be transferred to a vial with minimum head space. Storage and Stability: May be stored at RT for short-term only. Long-term storage is recommended at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. |
