Chemical Structure

Methyldifluorosilane CAS 420-34-8 chemical structure

Description

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

Methyldifluorosilane (CAS 420-34-8) is a high-purity analytical reference standard with the molecular formula CH4F2Si and a molecular weight of 82.12 g/mol.

Owing to fluorine substitution, Methyldifluorosilane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 82.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Methyldifluorosilane 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.
