L-4-Hydroxyphenyl-2,6-d2-alanine CAS 57746-15-3

Description

The occurrence of L-4-Hydroxyphenyl-2,6-d2-alanine is closely related to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

L-4-Hydroxyphenyl-2,6-d2-alanine (CAS 57746-15-3), molecular formula C9H9D2NO3 and molecular weight 183.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, L-4-Hydroxyphenyl-2,6-d2-alanine (C9H9D2NO3) contains deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 183.20 g/mol, it falls into the medium-molecular-weight range. 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.
