Description
4-Chloro-1-naphthol is a biochemistry-grade chromogenic reagent offered at a minimum purity of 97 %. It is registered under CAS number 604-44-4 and EG number 210-068-5, with empirical formula C₁₀H₇ClO and a molar mass of 178,62 g/mol. provides a practical quantity for preparing detection solutions used in peroxidase-linked immunoassays, blotting and related biochemical staining procedures. Upon enzymatic oxidation, the compound yields a coloured precipitate that enables visual or densitometric readout of target activity. Stated purity and molar mass facilitate consistent formulation of working reagents across experimental batches. Laboratories engaged in protein detection and enzyme-linked methods will find this grade suitable for routine and developmental work. Supplied from manufacturer Carl ROTH for biochemistry use, the product supports clear documentation of reagent identity in method records. Follow standard laboratory practice for dissolution and handling, and review the safety data sheet prior to first use.

Questions about 4-Chloro-1-naphthol, min. 97 %, for biochemistry, 5 g, glass
What is this article?
4-Chloro-1-naphthol, min. 97 %, for biochemistry, 5 g, glass 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.
Which category should I open next?
The category is Biochemicals & reagents. The sub-category is Biochemicals (other). The catalogue is Microbiology lab supplies.
