Description
CATO manufactures Diethyl Cyclobutane-1,1-dicarboxylate 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.
Diethyl Cyclobutane-1,1-dicarboxylate (CAS 3779-29-1), molecular formula C10H16O4 and molecular weight 200.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Diethyl Cyclobutane-1,1-dicarboxylate (C10H16O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 200.23 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
