Description
S-2-Nitrophenyl-L-cysteine is a cysteine derivative carrying an S-2-nitrophenyl substituent, supplied at a minimum purity of 90 % for biochemical and synthetic applications. The compound is registered under CAS number 60115-45-9 with the empirical formula C₉H₁₀N₂O₄S and a molar mass of 242,25 g/mol. It is Researchers select this modified amino acid when probing cysteine reactivity, protecting-group strategies or the design of chromophoric and electrophilic cysteine analogues. The defined molecular identity supports consistent dosing in organic and bioorganic protocols. Available from manufacturer Carl ROTH, the product integrates readily into laboratory catalogues focused on specialised amino acids and biochemical building blocks. Its compact pack and stated purity grade help laboratories manage inventory while maintaining experimental control in synthesis, conjugation and structure–activity studies. Clear CAS and formula data further simplify documentation, ordering and cross-referencing against literature procedures.

Questions about S-2-Nitrophenyl-L-cysteine, min. 90 %, 500 mg
What is this article?
S-2-Nitrophenyl-L-cysteine, min. 90 %, 500 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Microbiology lab supplies.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
