Chemical Structure
Description
The molecular framework of 2,2,4,4,6,6,8,8,10,10,12,12,14,14,16,16,18,18,20,20,22,22,24,24,26,26-Hexacosamethyl-1,3,5,7,9,11,13,15,17,19,21,23,25-tridecaoxa-2,4,6,8,10,12,14,16,18,20,22,24,26-tridecasilacyclohexacosane (C26H78O13Si13) 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.
CATO supplies 2,2,4,4,6,6,8,8,10,10,12,12,14,14,16,16,18,18,20,20,22,22,24,24,26,26-Hexacosamethyl-1,3,5,7,9,11,13,15,17,19,21,23,25-tridecaoxa-2,4,6,8,10,12,14,16,18,20,22,24,26-tridecasilacyclohexacosane (CAS 23732-94-7), a certified reference material (molecular formula C26H78O13Si13, MW 964.00 g/mol) for analytical method development and quality control.
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), 2,2,4,4,6,6,8,8,10,10,12,12,14,14,16,16,18,18,20,20,22,22,24,24,26,26-Hexacosamethyl-1,3,5,7,9,11,13,15,17,19,21,23,25-tridecaoxa-2,4,6,8,10,12,14,16,18,20,22,24,26-tridecasilacyclohexacosane 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.
