Chemical Structure

H-(2S,4R)-γ-Hydroxy-Glu-OH CAS 2485-33-8 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 H-(2S,4R)-γ-Hydroxy-Glu-OH.

CATO supplies H-(2S,4R)-γ-Hydroxy-Glu-OH (CAS 2485-33-8), a certified reference material (molecular formula C5H9NO5, MW 163.13 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, an amide group, H-(2S,4R)-γ-Hydroxy-Glu-OH is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.13 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.

As a certified reference material (CRM), H-(2S,4R)-γ-Hydroxy-Glu-OH 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.
