Description
CATO manufactures 2-(3-Chloro-5-hydroxyphenyl)acetic acid 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.
CATO supplies 2-(3-Chloro-5-hydroxyphenyl)acetic acid (CAS 149029-88-9), a certified reference material (molecular formula C8H7ClO3, MW 186.59 g/mol) for analytical method development and quality control.
2-(3-Chloro-5-hydroxyphenyl)acetic acid (C8H7ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
