Chemical Structure

Glycyl-DL-serine CAS 687-38-7 chemical structure

Description

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.

Glycyl-DL-serine (CAS 687-38-7) is a high-purity analytical reference standard with the molecular formula C5H10N2O4 and a molecular weight of 162.14 g/mol.

Owing to a carbohydrate-derived structure, an amide group, Glycyl-DL-serine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.14 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.
