Description
As a certified reference material (CRM), 122872-03-1 Azuleno[6,5-b]furan-2(3H)-one,decahydro-5-hydroxy-4a,8-dimethyl-3-methylene-, [3aR-(3aa,4ab,5b,7aa,8a,9ab)]- (9CI) 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.
122872-03-1 Azuleno[6,5-b]furan-2(3H)-one,decahydro-5-hydroxy-4a,8-dimethyl-3-methylene-, [3aR-(3aa,4ab,5b,7aa,8a,9ab)]- (9CI) (CAS 122872-03-1), molecular formula C15H22O3 and molecular weight 250.33 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 122872-03-1 Azuleno[6,5-b]furan-2(3H)-one,decahydro-5-hydroxy-4a,8-dimethyl-3-methylene-, [3aR-(3aa,4ab,5b,7aa,8a,9ab)]- (9CI) (C15H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 250.33 g/mol, it falls into the medium-molecular-weight range. 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.
