Chemical Structure

1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with 1,3,5-trimethoxy-1,5-dimethyl-1,3,5-triphenyltrisiloxane CAS 68992-19-8 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.

CATO supplies 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with 1,3,5-trimethoxy-1,5-dimethyl-1,3,5-triphenyltrisiloxane (CAS 68992-19-8), a certified reference material (molecular formula C23H30O5Si3C6H14O3, MW 604.92 g/mol) for analytical method development and quality control.

The molecular framework of 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with 1,3,5-trimethoxy-1,5-dimethyl-1,3,5-triphenyltrisiloxane (C23H30O5Si3C6H14O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with 1,3,5-trimethoxy-1,5-dimethyl-1,3,5-triphenyltrisiloxane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
