Bromochlorophenol Blue : Use & Applications

Bromochlorophenol blue is a chemical compound commonly used as a pH indicator. It has applications in various industries, including chemistry, biology, and medical research. A dye that has been used as an industrial dye, a laboratory indicator, and a biological stain. The Bromochlorophenol Blue Dye finds extensive use in several applications. It is used as a tracking dye in protein electrophoresis, the Bromochlorophenol Blue dye migrates alongside the protein samples, allowing for easy tracking and visualization of the electrophoretic run. This dye is commonly employed as a pH indicator due to its color changes in response to different pH levels. The Bromochlorophenol Blue Dye is utilized in complexometric titrations to indicate the endpoint of the reaction by changing color, providing a visual indicator of the completion of the titration process. This dye serves as a critical component in various colorimetric assays, allowing for the quantitative measurement of specific compounds or substances through the observation of color changes. With its well-defined color changes, Bromochlorophenol Blue Dye is often employed as an indicator in a broad range of chemical reactions, enabling the detection of various analytes and reaction endpoints. With its extensive range of applications, our Bromochlorophenol Blue Dye is an indispensable tool in many scientific fields. Bromochlorophenol blue is an antimicrobial agent that is used in clinical chemistry and analytical chemistry. Bromochlorophenol blue also reacts with hydroxide solution to produce a blue color, which can be detected by flow assay.

    We ship free-of-cost samples (freight free) for all our products. In fact, we recommend to approve a pre-shipment sample before purchase of product.
    The globally accepted specifications of Merck, Sigma-Aldrich and ACS are the benchmark for all our products. And we surpass the benchmark for all our products.
    We provide all the technical assistance in testing the product by providing detailed Method-of-Analysis, standard spec copy, any benchmark data if available. We also, assist with live testing of the product. We do not believe in room for ambiguity, hence, all assistance is provided till customer is satisfied with the end result.
    With a team of profound expertise, we have hands-on experience of closely working with Unilever, Milliken, DKSH, Biosynth, Sigma Aldrich (now Merck) and many more industry leaders to jointly develop some exceptional and one of the most innovative Healthcare products.
    Almost all of the products are available in stock in bulk quantities. In a rare case, we take a couple of weeks for preparation.
    We strive to provide the purest form of the compound. However, we welcome our customer’s in-house specs and try our best to suffice their in-house spec compliance.
    Yes, we gladly welcome the procurement and R&D team to visit our manufacturing facility for audit and even to run trials for product development and application. What are the various streams of products manufactured by you?
    We started with a couple of pH Indicators and Biological Stains, but over the last 40 years, we have expanded to Life Science products, pH Indicators, Complexometric Indicators, and even Specialty Colors which have a specialised performance driven application.
    We have a dedicated 1600 sqft research and development division for development of different molecules belonging to color changing chemistry which help in development of innovative end-use applications in different products.
    We are extremely sensitive towards the environment and polluted water generated from processes is self treated using MVR distillation process at our facility ensuring zero discharge.
    We generally submit quotes of freight. On approval, we dispatch goods and keep consignee updated with shipment status at every step. Alternatively, we also ship on customer’s courier account.
    We usually submit a Pre-shipment Sample to customer for quality approval. Although, most customer prefer a simple COA approval, but we insist on sample approval to avoid all post-commercial shipment hiccups.
    Though, its a rare case (Since all products are mostly ready in stock), we usually intimate buyer of the lead time for preparation of the product. Buyer is updated with the status from time to time. Once product is ready, a PSS is sent for quality approval. On approval, we dispatch the product.
    For every inquiry of the product received, we send the pre-shipment sample representing the lot for quality approval. Only after approval, the commercial shipments are dispatched. Any issues in the quality of the product are resolved at the sampling stage. For the test of the sample, all assistance is provided from our end, with sufficient data and documentation. This has helped us fireproof the quality-related issues and have faced negligible rejections so far.
