Chemical Structure
Description
The occurrence of 1-(2-chloro-6-hydroxyphenyl)ethan-1-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2-chloro-6-hydroxyphenyl)ethan-1-one (CAS 55736-04-4) is a high-purity analytical reference standard with the molecular formula C8H13ClO2 and a molecular weight of 176.64 g/mol.
1-(2-chloro-6-hydroxyphenyl)ethan-1-one (C8H13ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 1-(2-chloro-6-hydroxyphenyl)ethan-1-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.
