Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Trimethyl(phenylselanyl)silane.
CATO supplies Trimethyl(phenylselanyl)silane (CAS 33861-17-5), a certified reference material (molecular formula C9H14SeSi, MW 229.25 g/mol) for analytical method development and quality control.
The molecular framework of Trimethyl(phenylselanyl)silane (C9H14SeSi) is characterized by an organic framework. 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).
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 Trimethyl(phenylselanyl)silane 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.
