Description

As a certified reference material (CRM), 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecafluoro-1,8-diiodooctane 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecakis(fluoranyl)-1,8-bis(iodanyl)octane 335-70-6 A821850 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecafluoro-1,8-diiodooctane 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecakis(fluoranyl)-1,8-bis(iodanyl)octane 335-70-6 A821850 (CAS 335-70-6), molecular formula C8F16I2 and molecular weight 653.87 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecafluoro-1,8-diiodooctane 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecakis(fluoranyl)-1,8-bis(iodanyl)octane 335-70-6 A821850 (C8F16I2) is characterized by fluorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
