Chemical Structure

Ethyltrichlorosilane CAS 115-21-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 163.51 g/mol gives Ethyltrichlorosilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyltrichlorosilane (CAS 115-21-9), molecular formula C2H5Cl3Si and molecular weight 163.51 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyltrichlorosilane (C2H5Cl3Si) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 163.51 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures Ethyltrichlorosilane 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.
