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-Fluoro-2-methyl-4-(3-methylbut-3-en-1-yl)benzene.
CATO supplies 1-Fluoro-2-methyl-4-(3-methylbut-3-en-1-yl)benzene (CAS 1305324-31-5), a certified reference material (molecular formula C12H15F, MW 178.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H15F, 1-Fluoro-2-methyl-4-(3-methylbut-3-en-1-yl)benzene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 178.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
