Chemical Structure

3-Butynyl Methanesulfonate CAS 72486-09-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Butynyl Methanesulfonate.

CATO supplies 3-Butynyl Methanesulfonate (CAS 72486-09-0), a certified reference material (molecular formula C5H8O3S, MW 148.18 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Butynyl Methanesulfonate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
