Description
CATO supplies Tetramethyl tetra-3-trifluoropropyl cyclotetrasiloxane (CAS 429-67-4), a certified reference material (molecular formula C16H28F12O4Si4, MW 624.71 g/mol) for analytical method development and quality control.
Tetramethyl tetra-3-trifluoropropyl cyclotetrasiloxane (C16H28F12O4Si4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Tetramethyl tetra-3-trifluoropropyl cyclotetrasiloxane 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.
