Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Bis(chlorodimethylsilyl)benzene.
CATO supplies 1,4-Bis(chlorodimethylsilyl)benzene (CAS 1078-97-3), a certified reference material (molecular formula C10H16Cl2Si2, MW 263.31 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, 1,4-Bis(chlorodimethylsilyl)benzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 1,4-Bis(chlorodimethylsilyl)benzene 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.
