Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.20 g/mol gives Nitroso L-Arginine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Nitroso L-Arginine (CAS 2492451-27-9), molecular formula C6H13N5O3 and molecular weight 203.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Nitroso L-Arginine (C6H13N5O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 203.20 g/mol, it falls into the medium-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.
