Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,9-Diazaspiro[5.5]Undecane-2,4-dione dihydrochloride.
3,9-Diazaspiro[5.5]Undecane-2,4-dione dihydrochloride (CAS 1609402-96-1), molecular formula C9H14N2O2HCl and molecular weight 218.68 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,9-Diazaspiro[5.5]Undecane-2,4-dione dihydrochloride (C9H14N2O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 218.68 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 3,9-Diazaspiro[5.5]Undecane-2,4-dione dihydrochloride 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.
