Chemical Structure
Description
As a certified reference material (CRM), (2S)-2-amino-2-{3-tert-butylbicyclo[1.1.1]pentan-1-yl}acetic acid 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.
(2S)-2-amino-2-{3-tert-butylbicyclo[1.1.1]pentan-1-yl}acetic acid (CAS 944313-19-3), molecular formula C11H19NO2 and molecular weight 197.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2S)-2-amino-2-{3-tert-butylbicyclo[1.1.1]pentan-1-yl}acetic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
