Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl (4,4-difluoro-1-oxaspiro[4.5]decan-8-yl)carbamate 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 (4,4-difluoro-1-oxaspiro[4.5]decan-8-yl)carbamate (CAS 2770344-61-9) is a high-purity analytical reference standard with the molecular formula C14H23F2NO3 and a molecular weight of 291.33 g/mol.
Structurally, tert-Butyl (4,4-difluoro-1-oxaspiro[4.5]decan-8-yl)carbamate (C14H23F2NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 291.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
