Description
L(+)-Amethopterin hydrate is a biochemical reagent offered at a minimum purity of 95 %, with CAS number 133073-73-1 and the empirical formula C₂₀H₂₂N₈O₅·H₂O. The compound has a molar mass of 454,44 g/mol, supporting accurate preparation of solutions and stoichiometric work in the laboratory. This hydrate form from manufacturer Carl ROTH provides a defined amethopterin (methotrexate-related) material for experimental protocols that require traceable identity and purity. Laboratories can use the stated formula and molar mass for stock formulation, reference standards and synthetic or assay development. The pack size balances practical working quantity with efficient inventory control for specialised reagents. Clear CAS designation and empirical composition facilitate documentation, quality records and scientific communication. Academic and industrial groups studying antifolate pathways, enzyme inhibition or related small-molecule chemistry will find the specification set practical for controlled laboratory handling and reproducible experimental design.

Questions about L(+)-Amethopterin hydrate, min. 95 %, 25 g
What is this article?
L(+)-Amethopterin hydrate, min. 95 %, 25 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
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.
