Chemical Structure

6-Ethynylthiochroman-4-one CAS 188889-25-0 chemical structure

Description

CATO manufactures 6-Ethynylthiochroman-4-one 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.

6-Ethynylthiochroman-4-one (CAS 188889-25-0), molecular formula C11H8OS and molecular weight 188.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Ethynylthiochroman-4-one (C11H8OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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