(S,E)-2-Amino-5-(2,3-dimethylguanidino)pentanoic Acid-13C5 CAS CATO-C4X-253613

Description

The occurrence of (S,E)-2-Amino-5-(2,3-dimethylguanidino)pentanoic Acid-13C5 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S,E)-2-Amino-5-(2,3-dimethylguanidino)pentanoic Acid-13C5 (CAS CATO-C4X-253613), a certified reference material (molecular formula C3[13C]5H18N4O2, MW 207.22 g/mol) for analytical method development and quality control.

The molecular framework of (S,E)-2-Amino-5-(2,3-dimethylguanidino)pentanoic Acid-13C5 (C3[13C]5H18N4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
