Description
L-Alanyl-L-glutamine is a dipeptide amino-acid derivative supplied as CELLPURE® grade with a minimum purity of 99 % for cell-culture applications. The compound is identified by CAS number 39537-23-0, empirical formula C₈H₁₅N₃O₄ and molar mass 217,22 g/mol; its boiling point is given as 360 °C. Relative to free glutamine, the alanyl-glutamine dipeptide offers a practical solid form for preparing stable supplements and defined media. This variant is The CELLPURE® material is available from manufacturer Carl ROTH and is intended for amino-acid use in cell-culture environments. Researchers can incorporate the dipeptide when formulating feeds or complete media that require a reliable glutamine source with documented purity. Consistent specification of CAS, formula and molar mass supports traceability in laboratory documentation and helps align reagent choice with established cell-culture protocols.

Questions about L-Alanyl-L-glutamine, min. 99 %, CELLPURE®, 5 g, plastic
What is this article?
L-Alanyl-L-glutamine, min. 99 %, CELLPURE®, 5 g, plastic 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.
