Description
Lacmoid is an analytical-grade (p.a.) laboratory reagent with CAS number 42249-61-6, empirical formula C₂₄H₁₆N₂O₆ and a molar mass of 428,39 g/mol. Listed under EG nr. 255-736-7, this compound is supplied for chemical and laboratory use where a defined p.a. quality lacmoid is required. offers a convenient quantity for analytical work, indicator-related applications and general reagent preparation at the bench. Available from manufacturer Carl ROTH, lacmoid is characterised by its documented molecular formula, molar mass and registry identifiers, supporting accurate labelling in inventories and method descriptions. The p.a. grade designation signals suitability for analytical laboratory practice rather than technical bulk use. Compact glass packaging helps maintain orderly storage and controlled dispensing in research, teaching and routine analytical environments. With clear CAS, EG and formula data, this lacmoid portion integrates cleanly into standard chemical catalogues and quality systems that demand traceable reagent identity.

Questions about Lacmoid, p.a., 5 g, glass
What is this article?
Lacmoid, p.a., 5 g, glass 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.
