PAR monosodium salt excellent quality manufacturer, exporter and supplier. 4-(2-Pyridylazo)resorcinol monosodium salt is a useful indicator in complexometry, as well as a reagent for the extraction and spectrophotometric determination of many transition compounds. It is a highly selective and sensitive reagent for cobalt and iron. 4-(2-Pyridylazo)resorcinol monosodium salt is also a useful reagent for selective determination of trace level chrome(III) by ion-pair reversed-phase high-performance liquid chromotography.

Orcinol excellent quality manuafacturer,exporter and supplier. Orcinol is extracted from archil lichen, Rocella tinctoria. It is then converted to orcein by ammonia and air. Orcein is a reddish-brown dye, orchil is a purple-blue dye. Orcein is also used as a stain in microscopy to visualize elastic fibers, Hepatitis B surface antigens and copper associated proteins. It is a mixture of phenoxazone derivates - hydroxyorceins, aminoorceins, and aminoorceinimines. It can be used to dye wool and silk, without the use of mordant. 

Orange G excellent quality manufacturer,exporter and supplier. Orange G is a synthetic azo dye used in histology in many staining formulations. It usually comes as a disodium salt. It has the appearance of orange crystals or powder. The main use of Orange G is in the OG-6 Papanicolaou stain, to stain keratin, however it is also a major component of the Alexander test for pollen staining. It is often combined with other yellow dyes and used to stain erythrocytes in the trichrome methods

NITROSO-R-SALT is a excellent quality manufacturer,exporter and supplier.

NILE RED excellent quality manufacturing, exporter and supplier. Nile red (also known as Nile blue oxazone) is a lipophilic stain. It is produced by boiling a solution of Nile blue with sulfuric acid. Nile red has applications in cell biology, where it can be used as a membrane dye which can be readily visualised using an epifluorescence microscope with excitation and emission wavelengths usually shared with RFP. Nile red is used to localize and quantitate lipids, particularly neutral lipid droplets within cells.

Nile Blue sulfate excellent quality manufacturer, exporter and supplier . Nile Blue sulfate is a highly fluorescent dye which has been found to lase in the 670-740 nm region. Nile Blue A is used to differentiate melanins and lipofuscins. Also useful for staining fats. Used in the preparation of an amperometric glucose sensor. Nile Blue Sulfate is a basic oxazine dye which is soluble in water and ethyl alcohol .

Nile Blue chloride excellent quality manufacturer, exporter and supplier. Nile Blue chloride is a fluorescence reference standard used for various histologic staining. It is commonly utilized in studies involved with lipid and nuclei staining. Nile Blue chloride imparts a pink color to unsaturated glycerides and neutral lipids and stains nuclei and acids (such as fatty acids, chormolipids and phospholipids) a purple-blue color.

NEUTRAL RED 95 % excellent quality manufacturer, exporter and supplier. Neutral red is a eurhodin dye used for staining in histology. 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. In microbiology, it is used in the MacConkey agar and broth media to differentiate bacteria for lactose fermentation. Neutral red is added to some growth media for bacterial and cell cultures. Neutral red acts as a pH indicator, changing from red to yellow between pH 6.8 and 8.0.

METHYL ORANGE ACS GRADE excellent quality manufacturer, exporter and supplier. METHYL ORANGE ACS GRADE is an azo dye which works as a pH indicator.

Colour change 

The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator itself. Recall that pH indicators are not only natural dyes but also weak acids. The dissociation of the weak acid indicator causes the solution to change color.

Specifications :-

   Transition range: pH 3.1 - pH 4.4pink - orange yellow
