Chemical Structure
Description
The occurrence of 1-Chloro-4-(5-(penta-1,3-diyn-1-yl)thiophen-2-yl)but-3-yn-2-ol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Chloro-4-(5-(penta-1,3-diyn-1-yl)thiophen-2-yl)but-3-yn-2-ol (CAS 26905-70-4), a certified reference material (molecular formula C13H9ClOS, MW 248.73 g/mol) for analytical method development and quality control.
The molecular framework of 1-Chloro-4-(5-(penta-1,3-diyn-1-yl)thiophen-2-yl)but-3-yn-2-ol (C13H9ClOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 1-Chloro-4-(5-(penta-1,3-diyn-1-yl)thiophen-2-yl)but-3-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.
