Description
CATO manufactures Tert-butyl 2-(3,9-diazaspiro[5.5]Undecan-3-yl)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Tert-butyl 2-(3,9-diazaspiro[5.5]Undecan-3-yl)acetate (CAS 189333-51-5), molecular formula C15H28N2O2 and molecular weight 268.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tert-butyl 2-(3,9-diazaspiro[5.5]Undecan-3-yl)acetate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
