1-methylprop-2-ynylcyclobutane CAS 2137659-03-9

Description

Compared with other compounds in its class, the molecular weight of 108.18 g/mol gives 1-methylprop-2-ynylcyclobutane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-methylprop-2-ynylcyclobutane (CAS 2137659-03-9), molecular formula C8H12 and molecular weight 108.18 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-methylprop-2-ynylcyclobutane (C8H12) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 108.18 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
