Chemical Structure

Trichlorosilane CAS 10025-78-2 chemical structure

Description

The occurrence of Trichlorosilane is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Trichlorosilane (CAS 10025-78-2), a certified reference material (molecular formula Cl3Si, MW 134.44 g/mol) for analytical method development and quality control.

The molecular framework of Trichlorosilane (Cl3Si) is characterized by chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
