Z-DL-Phe-ONB, also known as Z-DL-phenylalanine-ONB, is a chemical compound that consists of a phenylalanine residue with a 9-fluorenylmethoxycarbonyl (Fmoc) protecting group and a 2-nitrobenzyl (ONB) side chain. Z-DL-Phe-ONB is commonly used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS), where the Fmoc group serves as a protecting group for the amino acid's side chain, allowing for selective deprotection and coupling reactions. The ONB side chain, on the other hand, can be used for photolabile protection, enabling the release of the peptide from the resin support upon exposure to UV light. Z-DL-Phe-ONB is a valuable tool in the field of peptide chemistry, facilitating the synthesis of complex peptide sequences with controlled release mechanisms.
The CAS Registry Mumber 96092-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,0,9 and 2 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 96092-61: (7*9)+(6*6)+(5*0)+(4*9)+(3*2)+(2*6)+(1*1)=154 154 % 10 = 4 So 96092-61-4 is a valid CAS Registry Number.
