Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(But-3-en-1-yl)-1,4-difluorobenzene.
CATO supplies 2-(But-3-en-1-yl)-1,4-difluorobenzene (CAS 951892-23-2), a certified reference material (molecular formula C10H10F2, MW 168.18 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, an aromatic ring system, 2-(But-3-en-1-yl)-1,4-difluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.18 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.
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.
