Aurin, also known as P-Rosolic Acid, is a synthetic dye with the chemical formula C19H14O3 and a molecular weight of 290.32 g/mol. It carries the CAS number 603-45-2 and Colour Index number 43800, and is supplied by Karan Labortes with a dye content exceeding 85% as verified by spectrophotometry. The product exhibits a clear solution when dissolved at 0.1% concentration in ethanol, with an absorption maximum between 482 and 487 nm in ethanol with 5 ml of 1N HCl.
This dye is typically used in laboratory and industrial applications where precise color metrics are required. Its absorptivity, measured as A1%/1cm in the same solvent system, exceeds 2000, indicating strong light absorption at the specified wavelength. Standard dye-grade materials like Aurin are often evaluated for loss on drying at 110°C, a common test to assess moisture content and stability under thermal conditions.
Aurin finds applications in chemical analysis, histology, and as a pH indicator due to its color-changing properties in different pH environments. Importers sourcing from Karan Labortes in Mumbai should confirm packaging formats and bulk handling procedures, as dye content and solubility are critical for end-use performance. The product is suitable for buyers in pharmaceuticals, research labs, and specialty chemical sectors.

Before placing an order for Aurin (P-Rosolic Acid) from Karan Labortes, verify the dye content and solubility specifications match your application requirements. Confirm the absorption maximum and absorptivity values, as these directly impact performance in laboratory or industrial settings. Request a certificate of analysis to validate the product’s purity and consistency with the listed specifications.
Discuss logistics details such as packaging, shipping methods, and Incoterms with the supplier. Aurin is typically shipped in sealed containers to prevent moisture absorption, which could affect its loss on drying value. Clarify lead times and whether the supplier can accommodate bulk orders, as this may influence your production schedule.
Conduct quality checks upon receipt, including testing solubility in ethanol and measuring the absorption spectrum. Inspect the packaging for signs of damage or tampering, and ensure all documentation, including the certificate of analysis, is provided. For critical applications, consider third-party testing to confirm the dye content and other key specifications.
