Chemical Structure

Tetradecamethylcycloheptasiloxane CAS 107-50-6 chemical structure

Description

The occurrence of Tetradecamethylcycloheptasiloxane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tetradecamethylcycloheptasiloxane (CAS 107-50-6), a certified reference material (molecular formula C14H42O7Si7, MW 519.08 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Tetradecamethylcycloheptasiloxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 519.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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 manufactures Tetradecamethylcycloheptasiloxane 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.
