Chemical Structure
Description
As a certified reference material (CRM), 1,2,3-Tribromo-1,1,2,3,3-pentamethyltrisilane 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.
CATO supplies 1,2,3-Tribromo-1,1,2,3,3-pentamethyltrisilane (CAS 127725-93-3), a certified reference material (molecular formula C5H15Br3Si3, MW 399.14 g/mol) for analytical method development and quality control.
Owing to bromine substitution, 1,2,3-Tribromo-1,1,2,3,3-pentamethyltrisilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.14 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.
