Chemical Structure

2,9-diazaspiro[5.5]undecan-1-one hydrochloride CAS 1187173-73-4 chemical structure

Description

2,9-diazaspiro[5.5]undecan-1-one hydrochloride (CAS 1187173-73-4), molecular formula C9H16N2OHCl and molecular weight 204.70 g/mol, is a CATO reference standard with documented purity and traceability.

2,9-diazaspiro[5.5]undecan-1-one hydrochloride (C9H16N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2,9-diazaspiro[5.5]undecan-1-one hydrochloride 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.
