Description
L-Lysine hydrochloride, min. 98,5 %, is an amino acid hydrochloride salt supplied for biochemistry applications and meeting USP requirements. It is identified by CAS number 657-27-2 and EG nr. 211-519-9, with the empirical formula C₆H₁₅ClN₂O₂, a molar mass of 182,65 g/mol and a density of 1,28 g/cm³. This material supports laboratory work in analytical chemistry and food analysis, including nitrogen determination according to Kjeldahl, where a defined lysine salt is required as a reference or reagent component. The grade is specified as min. 98,5 % and intended for biochemistry use under USP designation, giving clear identity and purity information for method documentation. Manufactured by Carl ROTH, L-lysine hydrochloride integrates readily into standard biochemical workflows that rely on essential amino acids. Its well-characterised physical data facilitate calculation of molar concentrations and formulation of buffers or calibration mixtures without additional conversion steps.

Questions about L-Lysine hydrochloride, min. 98,5 %,, Ph.Eur., USP, JP, for biochemistry, 100 g
What is this article?
L-Lysine hydrochloride, min. 98,5 %,, Ph.Eur., USP, JP, for biochemistry, 100 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 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.
