For pharmaceutical companies and research institutions focused on developing advanced respiratory medications, sourcing critical intermediates like 8-Benzyloxy-5-(2-bromoacetyl)-2-hydroxyquinoline (CAS 100331-89-3) is paramount. This compound, often referred to as an Indacaterol intermediate, plays a pivotal role in the synthesis of potent beta-2 adrenoreceptor agonists. As a procurement manager or research scientist, understanding what to look for in a supplier is crucial for ensuring the quality, consistency, and cost-effectiveness of your drug development pipeline. This guide aims to shed light on key considerations when you need to buy this essential chemical.

Understanding the Intermediate's Significance
8-Benzyloxy-5-(2-bromoacetyl)-2-hydroxyquinoline is a complex organic molecule that serves as a fundamental building block. Its specific chemical structure allows for precise reactions, leading to the formation of active pharmaceutical ingredients (APIs) like Indacaterol, which is used to treat Chronic Obstructive Pulmonary Disease (COPD). The quality of this intermediate directly impacts the purity and efficacy of the final drug product. Therefore, selecting a reputable manufacturer is not just about price; it’s about ensuring the integrity of your end product.

Key Factors When Purchasing
When you are ready to purchase 8-Benzyloxy-5-(2-bromoacetyl)-2-hydroxyquinoline, several factors should guide your decision:

  • Purity and Specifications: Always demand a Certificate of Analysis (CoA) that clearly states the purity of the product, typically expected to be 98% or higher for pharmaceutical applications. Look for specifications regarding appearance, loss on drying, heavy metals, and individual impurity limits. A reliable supplier will readily provide this documentation.
  • Manufacturing Origin: While many countries produce chemical intermediates, China has emerged as a major hub for high-quality and competitively priced pharmaceutical raw materials. When seeking an 8-Benzyloxy-5-(2-bromoacetyl)-2-hydroxyquinoline supplier in China, prioritize those with established quality control systems and a proven track record.
  • Supplier Reputation and Reliability: Research the supplier’s history, certifications (e.g., ISO), and customer testimonials. A supplier with extensive experience in exporting pharmaceutical intermediates, like NINGBO INNO PHARMCHEM CO.,LTD., can offer valuable insights and ensure a smooth transaction. Their ability to provide consistent supply and responsive customer service is vital.
  • Pricing and Value: While cost is always a consideration, focus on the overall value. Competitive price for CAS 100331-89-3 should be balanced with guaranteed quality and reliable delivery. Bulk orders often come with discounts, so it’s beneficial to inquire about volume pricing from your chosen manufacturer.
  • Logistics and Packaging: Ensure the supplier adheres to proper packaging and shipping standards to maintain the product's integrity during transit. Clear communication regarding shipping terms (FOB, CFR, etc.) and delivery timelines is essential.

Finding a Reliable Manufacturer
To secure a consistent and high-quality supply of 8-Benzyloxy-5-(2-bromoacetyl)-2-hydroxyquinoline, consider engaging with experienced chemical suppliers who specialize in pharmaceutical intermediates. Look for manufacturers who offer comprehensive product information, transparent pricing, and dedicated customer support. By partnering with a qualified pharmaceutical intermediate manufacturer, you can confidently advance your drug development projects.
