Chemical Structure
Description
The occurrence of 2,4-Dichloro-5-methylphenol 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.
CATO supplies 2,4-Dichloro-5-methylphenol (CAS 1124-07-8), a certified reference material (molecular formula C7H6Cl2O, MW 177.03 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,4-Dichloro-5-methylphenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2,4-Dichloro-5-methylphenol 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.
