Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Bis(heptadecafluoro-1,1,2,2-tetrahydrodecyl)tetramethylsiloxane.
1,3-Bis(heptadecafluoro-1,1,2,2-tetrahydrodecyl)tetramethylsiloxane (CAS 129498-18-6) is a high-purity analytical reference standard with the molecular formula C24H20F34OSi2 and a molecular weight of 1026.53 g/mol.
The molecular framework of 1,3-Bis(heptadecafluoro-1,1,2,2-tetrahydrodecyl)tetramethylsiloxane (C24H20F34OSi2) is characterized by a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 1,3-Bis(heptadecafluoro-1,1,2,2-tetrahydrodecyl)tetramethylsiloxane 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.
