Description
Pigment yellow 191 is an organic yellow pigment grade supplied for laboratory and specialty chemical applications. It is identified by CAS number 129423-54-7, the empirical formula C₁₇H₁₅ClN₄O₇S₂Ca, and a molar mass of 527 g/mol. As a calcium-containing azo-type pigment structure, it is relevant to colourant research, formulation screening, analytical reference work, and materials studies that require a defined yellow organic pigment. size suits small-scale trials, spectroscopic checks, and comparative pigment evaluations without unnecessary surplus. Research groups in coatings, plastics colouration, ink development, or biochemical staining method work can use the material where a characterised Pigment Yellow 191 sample is specified. Sourced from manufacturer Carl ROTH under the chemicals and biochemicals offering, the product provides clear CAS and formula data for documentation and purchasing control. Consistent molecular descriptors support reproducible preparation of dispersions, standards, and test matrices in controlled laboratory settings.
This article is part of Primary antibodies, in Antibodies & ELISA kits.

Questions about Pigment yellow 191, 250 mg
What is this article?
Pigment yellow 191, 250 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Primary antibodies, inside Antibodies & ELISA kits, in Microbiology lab supplies.
A primary antibody binds the target. Host species, clonality, clone name if monoclonal, the antigen, and the applications it was shown in, such as Western blot or immunohistochemistry, are the specification. A pretty band in the wrong application is not a promise.
An antibody binds one target. A primary antibody binds the molecule of interest. A secondary antibody binds the primary and usually carries the signal, an enzyme or a dye. An ELISA kit is that binding arranged in a well so the amount of target becomes a colour. The host species, the clone, the antigen and the stated application are the specification. A name alone is not. The literature is on PubMed. Sequences of the targets are on NCBI Nucleotide. Reference material is catalogued by ATCC.
