Chemical Structure

2-Methylbutane-1,3-diol CAS 684-84-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 104.15 g/mol gives 2-Methylbutane-1,3-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methylbutane-1,3-diol (CAS 684-84-4), molecular formula C5H12O2 and molecular weight 104.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Methylbutane-1,3-diol (C5H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 104.15 g/mol, it falls into the low-molecular-weight range.

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.
