Chemical Structure
Description
The molecular framework of cis-1,3,3-Trichloro-1-propene (cis-trans mixture, ~70% Z) (C3H3Cl3) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
cis-1,3,3-Trichloro-1-propene (cis-trans mixture, ~70% Z) (CAS 2953-50-6), molecular formula C3H3Cl3 and molecular weight 145.41 g/mol, is a CATO reference standard with documented purity and traceability.
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.
