Chemical Structure

1,16-Difluorohexadecane CAS 408-41-3 chemical structure

Description

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.

1,16-Difluorohexadecane (CAS 408-41-3), molecular formula C29H51O5P and molecular weight 510.69 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,16-Difluorohexadecane (C29H51O5P) is characterized by a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 1,16-Difluorohexadecane 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.
