T-butyldichlorosilane CAS 85121-42-2 chemical structure

Description

T-butyldichlorosilane (CAS 85121-42-2), molecular formula C4H9Cl2Si and molecular weight 156.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, T-butyldichlorosilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.11 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), T-butyldichlorosilane 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.
