(R)-2-Amino-3-((5-(3-hydroxypropyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanoic acid CAS 571187-31-0

Description

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.

(R)-2-Amino-3-((5-(3-hydroxypropyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanoic acid (CAS 571187-31-0), molecular formula C14H18N4O3S and molecular weight 322.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (R)-2-Amino-3-((5-(3-hydroxypropyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), (R)-2-Amino-3-((5-(3-hydroxypropyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanoic 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.
