3- (4-Hydroxyphenyl) -D-Alanine CAS: 556-02-5
Product Name: 3-(4-Hydroxyphenyl)-D-alanine
CAS No.:

Formula: C9H11NO3

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.
