Description
N,N-Diisopropylethylamine (DIPEA) is a PEPTIPURE® base with minimum 99,5 % purity intended for peptide synthesis, including washing, deprotection and related coupling support steps. The empirical formula is C₈H₁₉N, molar mass 129,3 g/mol, density 0,754 g/cm³, boiling point 128,3 °C and flash point 12 °C. Identification data include CAS number 7087-68-5 and EG number 230-392-0. It is available from manufacturer Carl ROTH as part of the PEPTIPURE® range for peptide synthesis reagents. The combination of high stated purity and well-defined physical constants supports reproducible laboratory handling and process documentation. Transport classification is given by UN number 1992. Analytical and synthetic laboratories working on solid-phase or solution-phase peptides can use this DIPEA grade within established organic and peptide synthesis protocols that call for a strong, sterically hindered base.

Questions about N,N-Diisopropylethylamine (DIPEA), 100 ml, >=99,5 %, for peptide synthesis
What is this article?
N,N-Diisopropylethylamine (DIPEA), 100 ml, >=99,5 %, for peptide synthesis 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.
