Description
Fmoc-L-Asparagine, PEPTIPURE® is an Fmoc-protected L-asparagine building block with a minimum purity of 98,5 %, specified for biochemistry use. It is identified by CAS number 71989-16-7 and EG number 276-252-2, with empirical formula C₁₉H₁₈N₂O₅ and a molar mass of 354,36 g/mol. These data enable precise stoichiometric control in Fmoc solid-phase peptide synthesis and related coupling chemistry. The PEPTIPURE® grade supports laboratories that require consistent protected amino acids for sequence assembly, fragment condensation and method development. Clear molecular identity aids documentation in electronic lab notebooks and quality systems. This material from manufacturer Carl ROTH fits peptide chemistry workflows where asparagine incorporation must be reproducible across batches. Teams can align weighing, activation and deprotection steps with the stated assay and formula, supporting reliable production of research peptides, analogues and labelled constructs under controlled laboratory conditions.

Questions about Fmoc-L-Asparagine, PEPTIPURE®, min. 98,5 %, für die Biochemie, 5 g, glass
What is this article?
Fmoc-L-Asparagine, PEPTIPURE®, min. 98,5 %, für die Biochemie, 5 g, glass 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.
