Description
As a certified reference material (CRM), 2,8-diazaspiro[5.5]undecane 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.
CATO supplies 2,8-diazaspiro[5.5]undecane dihydrochloride (CAS 91188-28-2), a certified reference material (molecular formula C9H18N2HCl, MW 190.72 g/mol) for analytical method development and quality control.
The molecular framework of 2,8-diazaspiro[5.5]undecane dihydrochloride (C9H18N2HCl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
