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 Tert-butyl 5,5-difluoro-1,9-diazaspiro[5.5]Undecane-9-carboxylate.
CATO supplies Tert-butyl 5,5-difluoro-1,9-diazaspiro[5.5]Undecane-9-carboxylate (CAS 1892811-94-7), a certified reference material (molecular formula C14H24F2N2O2, MW 290.35 g/mol) for analytical method development and quality control.
The molecular framework of Tert-butyl 5,5-difluoro-1,9-diazaspiro[5.5]Undecane-9-carboxylate (C14H24F2N2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
