For businesses in the textile and chemical sectors, sourcing high-quality raw materials is paramount to product success. When it comes to vibrant and durable coloration for cotton fabrics, 1,5-Dibenzamidoanthraquinone (CAS 82-18-8) stands out as a critical component. This article serves as a comprehensive guide for procurement managers and R&D professionals looking to buy this essential anthraquinone dye, focusing on key considerations when dealing with suppliers, particularly from China.

Understanding 1,5-Dibenzamidoanthraquinone (CAS 82-18-8)

Known also by its C.I. designation Vat Yellow 3, 1,5-Dibenzamidoanthraquinone is recognized for its distinctive yellow powder appearance. Its primary application lies in the dyeing of cotton fabrics, where it imparts a stable and appealing yellow hue. Beyond its color, its performance is marked by excellent fastness properties, including high resistance to ironing, chlorine bleach, and light. This means that fabrics dyed with this compound maintain their color integrity even under demanding conditions. Furthermore, its chemical structure allows for interesting color shifts when exposed to varying pH levels, a characteristic that can be leveraged for specific dyeing effects.

Key Factors When Sourcing from a Manufacturer in China

When you intend to purchase 1,5-Dibenzamidoanthraquinone, selecting the right manufacturer and supplier is crucial. China is a global hub for chemical manufacturing, offering competitive pricing and extensive production capabilities. However, it’s essential to conduct thorough due diligence.

  • Product Purity and Specifications: Always request detailed product specifications, including purity levels, CAS number (82-18-8), and any relevant certifications (e.g., ISO). Ensure the product meets your application requirements, especially for sensitive uses like textile dyeing where consistency is key.
  • Supply Chain Reliability: A reliable supplier ensures consistent availability and timely delivery. Inquire about their production capacity, lead times, and inventory management. Understanding their logistical capabilities, including shipping ports like Shanghai or Qingdao, is also vital.
  • Pricing and Cost-Effectiveness: While Chinese suppliers often offer competitive pricing, it's important to compare quotes from multiple sources. Consider the total cost, including shipping and potential import duties, to determine the most cost-effective option. Understanding the price structure for bulk orders is a good negotiation strategy.
  • Quality Control and Compliance: Verify the supplier’s quality control processes and adherence to international standards. Look for suppliers who can provide safety data sheets (SDS) and assure compliance with environmental and safety regulations.

Leveraging 1,5-Dibenzamidoanthraquinone in Your Business

For businesses seeking to enhance their product offerings with reliable and high-quality dyes, sourcing 1,5-Dibenzamidoanthraquinone from a reputable manufacturer in China is a strategic move. By focusing on purity, reliability, and competitive pricing, you can ensure a stable supply of this vital fine chemical intermediate, supporting your production needs and ultimately contributing to the quality of your end products. Whether you are in large-scale production or specialized research, a diligent approach to sourcing will yield the best results.
