Chemical Structure

(<I>R</I>)-(-)-2-butanol CAS 14898-79-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 74.12 g/mol gives (<I>R</I>)-(-)-2-butanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (<I>R</I>)-(-)-2-butanol (CAS 14898-79-4), a certified reference material (molecular formula C4H10O, MW 74.12 g/mol) for analytical method development and quality control.

Structurally, (<I>R</I>)-(-)-2-butanol (C4H10O) contains 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 74.12 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.
