Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-((S)-1-((S)-2-Amino-5-guanidinopentanoyl)pyrrolidine-2-carboxamido)-3-phenylpropanoic acid.
(S)-2-((S)-1-((S)-2-Amino-5-guanidinopentanoyl)pyrrolidine-2-carboxamido)-3-phenylpropanoic acid (CAS 16874-80-9), molecular formula C20H30N6O4 and molecular weight 418.49 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-((S)-1-((S)-2-Amino-5-guanidinopentanoyl)pyrrolidine-2-carboxamido)-3-phenylpropanoic acid (C20H30N6O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
CATO manufactures (S)-2-((S)-1-((S)-2-Amino-5-guanidinopentanoyl)pyrrolidine-2-carboxamido)-3-phenylpropanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
