Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 159.44 g/mol gives 3,3,3-trichloro-2-methylprop-1-ene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,3,3-trichloro-2-methylprop-1-ene (CAS 4749-27-3), molecular formula C4H5Cl3 and molecular weight 159.44 g/mol, is a CATO reference standard with documented purity and traceability.
3,3,3-trichloro-2-methylprop-1-ene (C4H5Cl3) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
