Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Oxaspiro[5.5]undecane-4-carboxylic acid (CAS 1368153-21-2) is a high-purity analytical reference standard with the molecular formula C11H18O3 and a molecular weight of 198.26 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1-Oxaspiro[5.5]undecane-4-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.26 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).
CATO manufactures 1-Oxaspiro[5.5]undecane-4-carboxylic acid 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.
