When making procurement decisions for laboratory chemicals, two critical factors often guide the selection process: price and purity. For compounds like 5-Bromo-4-chloro-3-indolyl-beta-D-galactoside (CAS 7240-90-6), a crucial enzyme substrate used widely in biochemical and molecular biology applications, striking the right balance is essential. For B2B buyers, understanding where to buy and what to look for in a chemical manufacturer is key.

5-Bromo-4-chloro-3-indolyl-beta-D-galactoside, a white powder with a molecular weight of 408.63, serves as a chromogenic indicator for beta-galactosidase activity. Its effectiveness hinges on its purity; impurities can lead to false positives or negatives, compromising experimental results. Therefore, when considering purchase options, prioritizing suppliers who provide detailed Certificates of Analysis (CoA) is paramount. A reputable manufacturer will clearly state the purity level and confirm properties like solubility in 100 mM DMSO and its typical melting point of 230°C.

The price of 5-Bromo-4-chloro-3-indolyl-beta-D-galactoside can vary based on several factors, including the scale of production, the purity grade, and the supplier's location. Manufacturers in China, such as NINGBO INNO PHARMCHEM CO.,LTD., are often able to offer competitive pricing due to economies of scale and optimized production processes. When you decide to buy, getting quotes from several trusted chemical suppliers is a wise approach to ensure you are getting the best value for high-quality product.

It's also important to consider the supplier's reliability. A consistent supply chain and excellent customer service are as vital as the product itself. Buyers should look for manufacturers who can provide consistent batches, offer flexible packaging and shipping options, and are responsive to inquiries. This ensures that your procurement process is smooth and your research is not interrupted by supply chain issues. As a leading chemical supplier, we are dedicated to providing both exceptional purity and competitive pricing for CAS 7240-90-6.

In summary, when purchasing 5-Bromo-4-chloro-3-indolyl-beta-D-galactoside, always scrutinize the purity specifications and compare prices from reliable chemical manufacturers. Balancing these factors with consistent supply and dependable service will lead to successful procurement and reliable scientific outcomes.
