Description
O-Methyl-L-threonine is a protected threonine derivative offered at a minimum purity of 95 % for laboratory and biochemical applications. It is identified by CAS number 4144-02-9, with the empirical formula C₅H₁₁NO₃ and a molar mass of 133,15 g/mol. These identity parameters support accurate documentation in research notebooks, electronic lab systems, and purchasing records. The compound is Chemists and biochemists developing modified peptides, unnatural amino acid libraries, or specialised intermediates can use this grade in exploratory and scale-up experiments. The material is available from manufacturer Carl ROTH within its biochemicals assortment and is intended for professional laboratory use only. O-methylation on the threonine side chain alters hydrogen-bonding and polarity relative to native threonine, a modification frequently examined in medicinal chemistry and peptide design. Stated purity, CAS number, empirical formula, and molar mass help laboratories maintain consistent specifications across batches and projects. Handle the solid according to institutional chemical safety procedures and the information supplied with the product packaging.

Questions about O-Methyl-L-threonine, min. 95 %, 5 g
What is this article?
O-Methyl-L-threonine, min. 95 %, 5 g 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 Life Science & Microbiology.
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.
