Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Butanoic acid, 4-chloro-4-ethoxy-2-oxo-, ethyl ester (CAS 172314-57-7) is a high-purity analytical reference standard with the molecular formula C8H13ClO4 and a molecular weight of 208.64 g/mol.
The molecular framework of Butanoic acid, 4-chloro-4-ethoxy-2-oxo-, ethyl ester (C8H13ClO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Butanoic acid, 4-chloro-4-ethoxy-2-oxo-, ethyl ester 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.
