5-(4-Chlorophenyl)pent-4-yn-2-ol CAS 61899-21-6

Description

The occurrence of 5-(4-Chlorophenyl)pent-4-yn-2-ol is closely related to 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.

5-(4-Chlorophenyl)pent-4-yn-2-ol (CAS 61899-21-6), molecular formula C11H11ClO and molecular weight 194.66 g/mol, is a CATO reference standard with documented purity and traceability.

5-(4-Chlorophenyl)pent-4-yn-2-ol (C11H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 5-(4-Chlorophenyl)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.
