Chemical Structure

(S)-Pent-4-yn-2-ol CAS 81939-73-3 chemical structure

Description

The occurrence of (S)-Pent-4-yn-2-ol is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-Pent-4-yn-2-ol (CAS 81939-73-3), a certified reference material (molecular formula C5H8O, MW 84.12 g/mol) for analytical method development and quality control.

The molecular framework of (S)-Pent-4-yn-2-ol (C5H8O) is characterized by 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.

CATO manufactures (S)-Pent-4-yn-2-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
