Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Fmoc-L-Aspartic acid β-tert-butyl ester-<SUP>13</SUP>C<SUB>4</SUB>,<SUP>15</SUP>N (CAS 1217468-27-3) is a high-purity analytical reference standard with the molecular formula C19[13C]4H37[15N]O6 and a molecular weight of 428.51 g/mol.
Fmoc-L-Aspartic acid β-tert-butyl ester-<SUP>13</SUP>C<SUB>4</SUB>,<SUP>15</SUP>N (C19[13C]4H37[15N]O6) contains an amide group, a carboxylic acid 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. 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.
