Description
1,5-Diphenylcarbazide is an analytical redox indicator supplied at a minimum purity of 97 %, p.a., ACS. Identified by CAS number 140-22-7 and empirical formula C₁₃H₁₄N₄O, it has a molar mass of 242,28 g/mol and is used in colorimetric and redox analytical procedures. This grade meets p.a. and ACS requirements for laboratory work where defined purity supports reproducible titrations and spectrophotometric assays. Available from manufacturer Carl ROTH, 1,5-diphenylcarbazide is a classic choice among redox indicators for sensitive detection steps. The EG number is 205-403-7. Laboratories value this specification for consistent performance in analytical protocols that depend on clear colour transitions and reliable reagent quality. size balances day-to-day consumption with practical storage for research, quality-control and teaching environments focused on redox and colorimetric methods.

Questions about 1,5-Diphenylcarbazide, min. 97 %, p.a., ACS, 10 g, plastic
What is this article?
1,5-Diphenylcarbazide, min. 97 %, p.a., ACS, 10 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
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.
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?
