Bromoxylenol Blue (BXYB) is a sulfonphthalein dye used as a pH indicator, biological stain, and analytical reagent. It is particularly useful for detecting pH transitions in the acidic range and is applied in chemical analysis, microbiology, and laboratory titrations.

Cresyl Violet Acetate is a basic cationic dye commonly used in histology, cytology, and neuroscience research. It selectively binds to acidic tissue components, such as nucleic acids, and is particularly effective for staining neuronal cells and Nissl bodies in the nervous system.

Nile Blue Chloride is a cationic oxazine dye widely used as a biological stain, histological dye, and fluorescent indicator. It is best known for its ability to differentiate acidic and basic tissue components and to stain lipids, nuclei, and mitochondria with distinct color contrasts. In addition, it exhibits fluorescent properties, making it valuable in biological imaging and microscopy.

Nitroso R Salt is an azo-based metallochromic indicator dye widely used in analytical chemistry for detecting and quantifying metal ions, especially calcium (Ca²⁺) and magnesium (Mg²⁺). It is commonly applied in EDTA titrations and water hardness determination, forming distinct colored complexes that indicate titration endpoints.

Par Indicator Monosodium Salt is a water-soluble stain indicator used in analytical chemistry and laboratory applications. It functions primarily as a pH or metal ion indicator, helping detect endpoints in titrations or changes in solution chemistry. The monosodium salt form ensures high solubility and stability, making it suitable for precise and reproducible measurements.

Bromocresol Green Sodium Salt is the water-soluble sodium salt form of Bromocresol Green, a sulfonphthalein dye. It is widely used as a pH indicator, protein stain, and analytical reagent, especially in clinical chemistry for serum albumin determination.

Bromopyrogallol Red (BPR) is a triarylmethane dye derivative commonly used as a metal ion indicator, complexometric reagent, and pH indicator. In addition, it functions as a biological stain and an analytical reagent in laboratory studies. It is particularly valuable in detecting and quantifying certain metal ions through colorimetric and spectrophotometric methods.

Phenol Red (also known as phenolsulfonphthalein or PSP) is a pH indicator that is commonly sold in powder or crystalline form. Its appearance in this state is typically a bright red to dark red solid.

Pyrogallol Red is a triphenylmethane dye used as a stain and analytical indicator in laboratory applications. It is particularly known for forming colored complexes with metal ions, making it useful in complexometric titrations and metal ion detection

Brilliant Cresyl Blue is a basic cationic dye used primarily in hematology, cytology, and histology. It selectively stains reticulocytes, nucleic acids, and other acidic cellular components, making it valuable for blood and bone marrow analysis. The “65%” refers to the dye content, indicating laboratory-grade purity.

Sodium Diphenylamine Sulfonate is a chemical indicator widely used in analytical chemistry and laboratory applications. It functions as an oxidation-reduction (redox) indicator, producing a color change in response to the presence of oxidizing agents. 

Bromothymol Blue Sodium Salt is a pH indicator dye belonging to the sulfonphthalein family. It is the sodium salt form of Bromothymol Blue, which improves its water solubility and makes it suitable for use in aqueous solutions, buffer systems, and biological applications.
