Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tetraethyl pentane-1,1,5,5-tetracarboxylate (CAS 3779-30-4), molecular formula C20H29NO and molecular weight 299.45 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H29NO, Tetraethyl pentane-1,1,5,5-tetracarboxylate contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 299.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Tetraethyl pentane-1,1,5,5-tetracarboxylate 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.
