Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, pentacyclo[5.4.0.0^{2,6}.0^{3,10}.0^{5,9}]undecane-8-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies pentacyclo[5.4.0.0^{2,6}.0^{3,10}.0^{5,9}]undecane-8-carboxylic acid (CAS 1803561-83-2), a certified reference material (molecular formula C12H14O2, MW 190.24 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), pentacyclo[5.4.0.0^{2,6}.0^{3,10}.0^{5,9}]undecane-8-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
