FAQs of Alizarin Red S (13-22-3):


Q: How is Alizarin Red S commonly used in research laboratories?

A: Alizarin Red S is primarily used in histology and biochemistry for staining calcium deposits in tissue sections and as a chelometric indicator during analytical procedures. It is valued for its high sensitivity and specificity in detecting metal ions, particularly calcium.

Q: What is the benefit of using Alizarin Red S for histological staining?

A: The main benefit is its ability to selectively bind and visually highlight calcium deposits in tissues, producing a clear red coloration under a microscope. This facilitates accurate identification and study of mineralization processes in biological samples.

Q: When should Alizarin Red S be stored and handled with extra care?

A: Although Alizarin Red S is stable and non-hazardous under recommended conditions, it should always be stored in a cool, dry environment, away from excessive light. Standard laboratory precautions should be maintained to ensure safety and product longevity.

Q: What is the process for preparing an Alizarin Red S staining solution?

A: Typically, a 1% aqueous solution is prepared by dissolving the required amount of powder in distilled water, adjusting the pH to the desired range (4.15.2), and filtering before use for precise and consistent histological staining results.

Q: Where is the best place to purchase certified Alizarin Red S reagent?

A: Certified Alizarin Red S is available from leading distributors, exporters, and manufacturers in India. Products are supplied in HDPE bottles with a certificate of analysis included for each batch, ensuring compliance with analytical reagent standards.

Q: What is the regulatory and safety status of Alizarin Red S?

A: Alizarin Red S is not classified as a hazardous substance or mixture and does not require UN regulation for transport. It complies with analytical reagent standards and contains less than 0.002% lead, ensuring it is safe for standard laboratory use.

Q: How long is the shelf life of Alizarin Red S, and how should it be stored?
