Chemical Structure
Description
The occurrence of 1-Methyl-3-(3,3,3-trifluoropropyl)benzene is closely related to fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Methyl-3-(3,3,3-trifluoropropyl)benzene (CAS 1099597-71-3), molecular formula C10H11F3 and molecular weight 188.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, an aromatic ring system, 1-Methyl-3-(3,3,3-trifluoropropyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.19 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.
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.
