Eriochrome Blue Black B

ERIOCHROME BLUE BLACK B used for the determination of calcium, magnesium, manganese, zinc and other metal ions. It is a black fine crystalline powder. Eriochrome Blue Black B (EBBB) is a synthetic dye used as a complexometric indicator in titration and as a reagent in biochemical and physiological experiments. It is a member of the Eriochrome family, a group of dyes that are used to detect metal ions in aqueous solutions. EBBB is one of the most commonly used indicators in the laboratory due to its wide range of applications and its ability to detect a variety of metal ions. There are certain scientific research applications as follows: Dye Degradation and Water Treatment:Eriochrome Blue Black B has been studied for its degradation by chemical transformation and oligomerization using enzymes like horseradish peroxidase and biomimetic catalysts like hematin. This application is significant for water purification and environmental remediation processes. Photocatalytic Degradation:Cobalt chromite spinel nanoparticles have been used for the photocatalytic degradation of Eriochrome Black T (a related azo dye), illustrating potential applications in environmental pollution control. Analytical Chemistry and Spectrophotometry: The dye has been studied in the context of spectrophotometric titration, where its interactions with different substances are used to determine concentrations of various chemicals. Biochemical Applications: It has been used in a light-scattering technique for the rapid and sensitive determination of proteins, demonstrating its utility in biochemical analysis. Applications in Solar Energy:The effect of Eriochrome Black T concentrations on the efficiency of dye-sensitized solar cells has been explored, showing its potential in renewable energy technologies. Bacterial Spore Detection: A novel ratiometric colorimetric and fluorescent dual probe based on Eriochrome Black T-Eu3+ complex has been designed for detecting dipicolinic acid, a biomarker of bacterial spores, illustrating its application in microbiology and public health.

    frequently asked questions

    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.
