Chemical Structure

(2R)-but-3-en-2-ol CAS 33447-72-2 chemical structure

Description

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.

(2R)-but-3-en-2-ol (CAS 33447-72-2), molecular formula C4H8O and molecular weight 72.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, (2R)-but-3-en-2-ol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 72.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
