Product Name: 3-(4-Hydroxyphenyl)-D-alanine
CAS No.: 556-02-5
Formula: C9H11NO3
Synonyms: (R)-3-(p-Hydroxyphenyl)alanine;D-Tyrosin;(R)-2-Amino-3-(p-hydroxyphenyl)propionic acid;H-D-Tyr-OH;D-Tyrosine(556-02-5);
Usage:
D-Tyrosine, the stereoisomer to L-Tyrosine (T899975), is an amino acid used in various organic
syntheses for antibiotics. It is used in the synthesis of (-)-anisomycin, as well as BATSI (boronic acid transition state inhibitors) which act on β-lactamases. It has also been studied as an inhibitor of microbial growth on surfaces, reducing microbial attachment to hydrophillic glass and hydrophobic po lypropylene surfaces.
