Chemical Structure

Phenylmethylsiloxane-dimethylsiloxane copolymers cst 50 CAS 63148-52-7 chemical structure

Description

The occurrence of Phenylmethylsiloxane-dimethylsiloxane copolymers cst 50 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 Phenylmethylsiloxane-dimethylsiloxane copolymers cst 50 (CAS 63148-52-7), a certified reference material (molecular formula C7H14OSiC2H6OSi, MW 216.43 g/mol) for analytical method development and quality control.

The molecular framework of Phenylmethylsiloxane-dimethylsiloxane copolymers cst 50 (C7H14OSiC2H6OSi) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Phenylmethylsiloxane-dimethylsiloxane copolymers cst 50 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.
