Poly-L-glutamine CAS 26700-71-0

Description

Compared with other compounds in its class, the molecular weight of 146.14 g/mol gives Poly-L-glutamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Poly-L-glutamine (CAS 26700-71-0) is a high-purity analytical reference standard with the molecular formula C5H10N2O3 and a molecular weight of 146.14 g/mol.

Based on its molecular formula C5H10N2O3, Poly-L-glutamine contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 146.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
