Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 109.17 g/mol gives 3,3-Dimethyl-2-methylenebutanenitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,3-Dimethyl-2-methylenebutanenitrile (CAS 51789-52-7) is a high-purity analytical reference standard with the molecular formula C7H11N and a molecular weight of 109.17 g/mol.
Structurally, 3,3-Dimethyl-2-methylenebutanenitrile (C7H11N) contains a nitrile group. 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 109.17 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).
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.
