Congo red excellent quality manufacturer, exporter and supplier. Congo red is an organic compound, the sodium salt of 3,3′-([1,1′-biphenyl]-4,4′-diyl)bis(4-aminonaphthalene-1-sulfonic acid. It is an azo dye. Congo red is water-soluble, yielding a red colloidal solution; its solubility is greater in organic solvents. However, the use of Congo red has long been abandoned, primarily because of its carcinogenic properties.

p-XYLENOL BLUE excellent quality manufacturer, exporter and supplier.

Pyrocatechol violet (PV) excellent quality manufacturer, supplier and exporter. Pyrocatechol violet (PV) is a sulfone phthalein dye made from condensing two moles of pyrocatechol with one mole of o-sulfobenzoic acid anhydride. PV has indicator properties and forms complexes with metal ions, making it useful as a chelometric reagent. As it chelates metals, a generally blue to blue-violet complex forms. Cationic surfactants, such as cetylammonium bromide significantly shift the absorbance maximum to higher wave lengths due to the formation of a higher ligand-to-metal ratio.

NEUTRAL RED 60% excellent quality manufacturer, exporter and supplier. Neutral red 60% is a eurhodin dye used for staining in histology and acts as a pH indicator, changing from red to yellow between pH 6.8 and 8.0. It stains lysosomes red. It is used as a general stain in histology, as a counterstain in combination with other dyes, and for many staining methods.NEUTRAL RED 60% used as an indicator for preparing neutral red paper, and as a biological stain.
