Description

As a certified reference material (CRM), tert-Butyl 6-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methyl)-2-azaspiro[3.3]heptane-2-carboxylate 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.

tert-Butyl 6-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methyl)-2-azaspiro[3.3]heptane-2-carboxylate (CAS 2769820-89-3) is a high-purity analytical reference standard with the molecular formula C18H32BNO4 and a molecular weight of 337.26 g/mol.

The molecular framework of tert-Butyl 6-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methyl)-2-azaspiro[3.3]heptane-2-carboxylate (C18H32BNO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. 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.
