Description
CATO manufactures cis-Diethyl 2,2-dimethyl-1,3-dioxolane-4,5-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.
cis-Diethyl 2,2-dimethyl-1,3-dioxolane-4,5-dicarboxylate (CAS 56543-05-6), molecular formula C11H18O6 and molecular weight 246.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, cis-Diethyl 2,2-dimethyl-1,3-dioxolane-4,5-dicarboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
