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 (2,3-Difluoro-1,4-phenylene)bis(trimethylsilane).
CATO supplies (2,3-Difluoro-1,4-phenylene)bis(trimethylsilane) (CAS 867366-94-7), a certified reference material (molecular formula C12H20F2Si2, MW 258.46 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, (2,3-Difluoro-1,4-phenylene)bis(trimethylsilane) is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.46 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.
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.
