Description
L-Tyrosine tert-butyl ester is a protected amino acid derivative with CAS number 16874-12-7 and empirical formula C₁₃H₁₉NO₃. The tert-butyl ester protects the carboxylic acid of L-tyrosine, allowing selective reactions at the amino or phenolic sites during peptide synthesis and related organic transformations. Such building blocks are routinely used in solution-phase and solid-phase peptide chemistry as well as in the preparation of tyrosine-containing intermediates. This material from manufacturer Carl ROTH supports research groups that need a defined ester for method development, small-scale synthesis, and multi-step sequences relying on acid-labile protecting groups. quantity is convenient for repeated weighing while remaining easy to store and handle. Clear identity data—CAS number, formula, molar mass, and purity—aid documentation and quality tracking in chemical and biochemical laboratories. The product is intended for professional use in medicinal chemistry, biochemistry, and fine-chemical synthesis workflows.

Questions about L-Tyrosine tert-butyl ester, min. 90 %, 100 g
What is this article?
L-Tyrosine tert-butyl ester, min. 90 %, 100 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Amino acids & peptides, inside Organic chemicals & synthesis reagents, in Lab chemicals.
An amino acid or a peptide is specified by the sequence or the residue, the chirality, and for a peptide the purity and the salt form. L and D forms are different compounds. A trifluoroacetate salt and a hydrochloride salt weigh differently per mole of peptide.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
The category is Organic chemicals & synthesis reagents. The sub-category is Amino acids & peptides. The catalogue is Lab chemicals.
