Chemical Structure

(S)-2-Guanidinopropanoic acid CAS 1758-74-3 chemical structure

Description

CATO supplies (S)-2-Guanidinopropanoic acid (CAS 1758-74-3), a certified reference material (molecular formula C4H9N3O2, MW 131.13 g/mol) for analytical method development and quality control.

The molecular framework of (S)-2-Guanidinopropanoic acid (C4H9N3O2) 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.

As a certified reference material (CRM), (S)-2-Guanidinopropanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
