Chemical Structure

4-Pentynyl methanesulfonate CAS 68275-03-6 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.

4-Pentynyl methanesulfonate (CAS 68275-03-6) is a high-purity analytical reference standard with the molecular formula C6H10O3S and a molecular weight of 162.21 g/mol.

The molecular framework of 4-Pentynyl methanesulfonate (C6H10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
