Chemical Structure

(S)-(+)-2-Butanol CAS 4221-99-2 chemical structure

Description

Structurally, (S)-(+)-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.

CATO supplies (S)-(+)-2-Butanol (CAS 4221-99-2), a certified reference material (molecular formula C4H10O, MW 74.12 g/mol) for analytical method development and quality control.

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.
