Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 465.50 g/mol gives H-Ala-Ala-Ala-Tyr-Ala-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies H-Ala-Ala-Ala-Tyr-Ala-OH (CAS 107865-40-7), a certified reference material (molecular formula C21H31N5O7, MW 465.50 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, H-Ala-Ala-Ala-Tyr-Ala-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 465.50 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).
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.
