Chemical Structure

2-Methylhex-5-en-3-yn-2-ol CAS 690-94-8 chemical structure

Description

2-Methylhex-5-en-3-yn-2-ol (CAS 690-94-8) is a high-purity analytical reference standard with the molecular formula C7H10O and a molecular weight of 110.15 g/mol.

Structurally, 2-Methylhex-5-en-3-yn-2-ol (C7H10O) contains a hydroxyl group, an ether linkage. 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 110.15 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.
