<SC>DL</SC>-丙氨酸-2-<SUP>13</SUP>C CAS 201489-22-7

Description

Compared with other compounds in its class, the molecular weight of 90.09 g/mol gives <SC>DL</SC>-丙氨酸-2-<SUP>13</SUP>C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

<SC>DL</SC>-丙氨酸-2-<SUP>13</SUP>C (CAS 201489-22-7), molecular formula C2[13C]H7NO2 and molecular weight 90.09 g/mol, is a CATO reference standard with documented purity and traceability.

<SC>DL</SC>-丙氨酸-2-<SUP>13</SUP>C (C2[13C]H7NO2) 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.

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.
