Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 4-((4-(tert-butyl)benzyl)oxy)-3,5-dichlorobenzoate (CAS 866153-31-3) is a high-purity analytical reference standard with the molecular formula C19H20Cl2O3 and a molecular weight of 367.27 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 4-((4-(tert-butyl)benzyl)oxy)-3,5-dichlorobenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.27 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.
CATO manufactures Methyl 4-((4-(tert-butyl)benzyl)oxy)-3,5-dichlorobenzoate 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.
