H-Ala-Ala-Lys-OH (H-1415.0250) CAS 45243-22-9

Description

Compared with other compounds in its class, the molecular weight of 288.34 g/mol gives H-Ala-Ala-Lys-OH (H-1415.0250) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

H-Ala-Ala-Lys-OH (H-1415.0250) (CAS 45243-22-9) is a high-purity analytical reference standard with the molecular formula C12H24N4O4 and a molecular weight of 288.34 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, H-Ala-Ala-Lys-OH (H-1415.0250) is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
