The occurrence of 1-Pentene is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Pentene (CAS 109-67-1), molecular formula C5H10 and molecular weight 70.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an organic framework, 1-Pentene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 70.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
