In the chemical industry, particularly for applications requiring precise colorants, sourcing high-purity compounds like Acid Orange 10 (CAS 1936-15-8) is essential. Whether for textiles, paper, inks, or biological research, the quality and consistency of the dye directly impact the final product's performance. This guide is designed for chemical purchasers and R&D scientists to understand the critical factors when buying this important azo dye.

Acid Orange 10, also known as Orange G, is characterized by its bright orange powder appearance and good solubility in water. Its chemical designation and CAS number, 1936-15-8, are key identifiers for purchasers. The dye's molecular formula, C16H10N2Na2O7S2, and molecular weight of 452.37 g/mol provide fundamental chemical information. For buyers, understanding its properties such as pH range, water content, and insoluble matter is vital for ensuring it meets application-specific requirements.

The primary drivers for seeking high-purity Acid Orange 10 stem from its diverse applications. In textile manufacturing, purity affects dye uptake, shade brilliance, and fastness properties, especially on sensitive fibers like silk and wool. For paper and ink production, consistent color intensity and compatibility with other formulation ingredients are crucial. In biological staining, precise concentrations and minimal impurities are necessary for accurate visualization of cellular structures.

When you decide to purchase Acid Orange 10, your first step should be to identify reputable manufacturers and suppliers. Companies that specialize in chemical production, particularly those based in regions like China known for their manufacturing capacity, often offer competitive pricing and reliable quality. It is imperative to request a Certificate of Analysis (CoA) with each order. The CoA should detail the purity, common impurities, and other relevant specifications like heavy metal content, which can be critical for certain applications.

Furthermore, understanding the supplier's capability to provide consistent batches is key. Variations in dye content or the presence of unwanted by-products can lead to significant issues in manufacturing or research. Therefore, establishing a long-term relationship with a trusted supplier who demonstrates a commitment to quality control is highly recommended. Purchasing in bulk quantities can often lead to better pricing and ensures a more stable supply chain, preventing production delays.

Before making a large purchase, it is advisable to obtain samples of Acid Orange 10 from potential suppliers. This allows your technical team to conduct in-house testing and verify its performance in your specific application, whether it’s optimizing a textile dyeing recipe or validating a staining protocol. Comparative testing can help in selecting the most cost-effective and highest-performing product.

In conclusion, sourcing high-purity Acid Orange 10 requires diligence. By focusing on detailed specifications, requesting CoAs, evaluating supplier reliability, and testing samples, chemical purchasers can ensure they procure a quality product that meets their demanding needs. Partnering with a manufacturer that prioritizes quality and transparency will ultimately lead to more successful and efficient operations.
