Chemical Structure
Description
2,4-Dichloro-N-((2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-ylidene)methyl)benzamide (CAS 477885-66-8), molecular formula C14H11Cl2NO5 and molecular weight 344.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2,4-Dichloro-N-((2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-ylidene)methyl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.15 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-N-((2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-ylidene)methyl)benzamide 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.
