Chemical Structure

L-Erythrulose CAS 533-50-6 chemical structure

Description

The occurrence of L-Erythrulose is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

L-Erythrulose (CAS 533-50-6), molecular formula C4H8O4 and molecular weight 120.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H8O4, L-Erythrulose contains a carbohydrate-derived structure; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 120.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
