Chemical Structure

(2S,3R)-2-Amino-3-hydroxypentanoic acid CAS 10148-67-1 chemical structure

Description

As a certified reference material (CRM), (2S,3R)-2-Amino-3-hydroxypentanoic 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.

(2S,3R)-2-Amino-3-hydroxypentanoic acid (CAS 10148-67-1), molecular formula C5H11NO3 and molecular weight 133.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2S,3R)-2-Amino-3-hydroxypentanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.15 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.

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.
