Chemical Structure

1,1,3,3,5,5,7,7,9,9,11,11,13,13-Tetradecamethylheptasiloxane CAS 19095-23-9 chemical structure

Description

As a certified reference material (CRM), 1,1,3,3,5,5,7,7,9,9,11,11,13,13-Tetradecamethylheptasiloxane 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.

1,1,3,3,5,5,7,7,9,9,11,11,13,13-Tetradecamethylheptasiloxane (CAS 19095-23-9), molecular formula C14H42O6Si7 and molecular weight 503.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,3,3,5,5,7,7,9,9,11,11,13,13-Tetradecamethylheptasiloxane (C14H42O6Si7) is characterized by a carboxylic acid 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.

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.
