For businesses in the cosmetic, pharmaceutical, and diagnostic sectors, sourcing high-quality chemical ingredients is paramount. Erythrosine Sodium, a vibrant red dye with the CAS number 16423-68-0, is one such critical component. Understanding the nuances of purchasing this compound, especially from international markets like China, can significantly impact product quality and cost-effectiveness. This guide aims to provide procurement managers and R&D scientists with the essential information needed to buy Erythrosine Sodium efficiently.

Erythrosine Sodium is a xanthene dye, widely recognized for its intense red to brown powder appearance and its broad spectrum of applications. Its primary uses span across cosmetics, where it provides attractive coloration, and medical diagnostics, where it functions as a vital stain for specific cellular components. The chemical itself, with the molecular formula C20H6I4O5.2Na, is known for its stability and bright hue, making it a preferred choice for many formulators.

When looking to buy Erythrosine Sodium, quality is the first consideration. A reputable manufacturer in China will readily provide specifications detailing purity levels, often around 98%, and a Certificate of Analysis (COA) for each batch. This document confirms the product meets the required chemical and physical properties, including appearance and solubility. For procurement managers, verifying these details ensures that the purchased material will perform as expected in their specific applications, whether it's for a complex cosmetic formulation or a critical diagnostic assay.

The price of Erythrosine Sodium can vary based on purity, order volume, and the supplier's location and service offerings. Engaging directly with a supplier who has a strong manufacturing base in China often yields the most competitive pricing. It is advisable to request quotes from multiple suppliers to compare offers and negotiate favorable terms, especially for large-scale purchases. Understanding the lead times and shipping costs associated with international procurement is also crucial for effective supply chain management.

For research scientists and product formulators, the CAS number 16423-68-0 is a key identifier. Searching for this specific CAS number will help pinpoint accurate product listings and connect with reliable sources. Many Chinese chemical companies specialize in producing a wide array of fine chemicals, including dyes like Erythrosine Sodium, catering to a global clientele. Building a relationship with a trusted manufacturer can ensure a stable and consistent supply of this essential ingredient, supporting uninterrupted production and innovation.

In conclusion, when seeking to purchase Erythrosine Sodium, prioritize suppliers who offer high purity, comprehensive documentation, and competitive pricing. Leveraging the manufacturing capabilities within China can provide a strategic advantage. By conducting thorough research and direct communication with potential suppliers, businesses can secure a consistent and cost-effective supply of Erythrosine Sodium, empowering their product development and manufacturing processes.
