Chemical Structure

Chlorotrimethyl-d9-silane CAS 20395-57-7 chemical structure

Description

CATO manufactures Chlorotrimethyl-d9-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.

Chlorotrimethyl-d9-silane (CAS 20395-57-7), molecular formula C3D9ClSi and molecular weight 117.70 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3D9ClSi, Chlorotrimethyl-d9-silane contains deuterium isotope labeling, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 117.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
