Chemical Structure

Ethyl (S)-2-amino-3,3-dimethylbutanoate CAS 69557-34-2 chemical structure

Description

Ethyl (S)-2-amino-3,3-dimethylbutanoate (CAS 69557-34-2), molecular formula C8H17NO2 and molecular weight 159.23 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl (S)-2-amino-3,3-dimethylbutanoate (C8H17NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Ethyl (S)-2-amino-3,3-dimethylbutanoate 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.
