Chemical Structure
Description
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.
<SC>L</SC>-Ornithine-<SUP>13</SUP>C<SUB>5</SUB> hydrochloride (CAS 943962-21-8) is a high-purity analytical reference standard with the molecular formula [13C]5H12N2O2 HCl and a molecular weight of 120.58 g/mol.
Based on its molecular formula [13C]5H12N2O2 HCl, <SC>L</SC>-Ornithine-<SUP>13</SUP>C<SUB>5</SUB> hydrochloride contains chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 120.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
