Chemical Structure
Description
As a certified reference material (CRM), 5-Methoxy-2,3-dihydrospiro[indene-1,2'-pyrrolidine] 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.
5-Methoxy-2,3-dihydrospiro[indene-1,2'-pyrrolidine] (CAS 1211592-82-3), molecular formula C13H17NO and molecular weight 203.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Methoxy-2,3-dihydrospiro[indene-1,2'-pyrrolidine] is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 203.28 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
