Description
4-Methylumbelliferone is a coumarin-derived compound offered at a minimum purity of 94 % for biochemistry applications. It is identified by CAS number 90-33-5 and EG nr. 201-986-7, with the empirical formula C₁₀H₈O₃ and a molar mass of 176,17 g/mol. This from manufacturer Carl ROTH supports fluorescence-based assays, enzymatic activity measurements and use as a reference standard or synthetic intermediate in biochemical research. Many protocols rely on 4-methylumbelliferone because enzymatic cleavage of its glycosides and related conjugates releases a strongly fluorescent product, enabling sensitive kinetic readouts and high-throughput screening formats. The defined minimum assay together with explicit CAS and molar-mass data simplifies preparation of stock solutions, calibration curves and method documentation. Compact plastic packaging is practical for repeated bench-scale weighing under standard laboratory conditions. Handle the powder with usual precautions for fine organic solids, avoid unnecessary dust generation and keep the container closed when not in use. Review the safety data sheet for classification, recommended personal protective equipment and first-aid guidance before solution preparation or larger-scale weighing.

Questions about 4-Methylumbelliferone, min. 94 %, for biochemistry, 50 g, plastic
What is this article?
4-Methylumbelliferone, min. 94 %, for biochemistry, 50 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
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.
