The occurrence of 4-Chloroheptane is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloroheptane (CAS 998-95-8), molecular formula C7H15Cl and molecular weight 134.65 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloroheptane (C7H15Cl) 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.
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.
