Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 148.12 g/mol gives <SC>L</SC>-Glutamic acid-3-<SUP>13</SUP>C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies <SC>L</SC>-Glutamic acid-3-<SUP>13</SUP>C (CAS 115473-51-3), a certified reference material (molecular formula C4[13C]H9NO4, MW 148.12 g/mol) for analytical method development and quality control.
Structurally, <SC>L</SC>-Glutamic acid-3-<SUP>13</SUP>C (C4[13C]H9NO4) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 148.12 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
