Bromophenol Blue Sodium Salt, identified by CAS number 34725-61-6, is a remarkably versatile chemical compound widely utilized in both analytical chemistry and life sciences. Its distinctive properties allow it to function effectively as both a pH indicator and a visual tracking dye in gel electrophoresis. For researchers and laboratory professionals seeking reliable chemical reagents, understanding the nuances of its applications is key to optimizing experimental outcomes. As a leading manufacturer and supplier based in China, we are dedicated to providing high-quality Bromophenol Blue Sodium Salt to meet diverse laboratory needs.

As a pH indicator, Bromophenol Blue Sodium Salt exhibits a distinct color transition within a specific pH range. It typically changes from yellow in acidic conditions to blue in alkaline conditions, with its transition range falling between pH 3.0 and 4.6. This sharp and reversible color change makes it an invaluable tool for titrations and other analytical procedures where precise pH monitoring is required. When purchasing pH indicators, it's crucial to consider the purity and consistency of the product to ensure accurate readings. Many scientists look for a reliable supplier in China to source these essential reagents at competitive prices.

Beyond its role as a pH indicator, Bromophenol Blue Sodium Salt is extensively employed as a tracking dye in gel electrophoresis, particularly for nucleic acids and proteins. During electrophoresis, a negatively charged molecule is needed to migrate through the gel matrix, allowing researchers to monitor the progress of the separation. Bromophenol Blue Sodium Salt, carrying a slight negative charge at typical electrophoresis buffer pH, serves this purpose admirably. It migures through the gel at a rate comparable to DNA fragments of a specific size range, providing a visual cue to the running front. This allows for timely stopping of the electrophoresis run and prevents the sample from running off the gel. When sourcing electrophoresis supplies, procuring high-quality tracking dyes from reputable manufacturers ensures optimal visualization and experimental success.

The ability to buy Bromophenol Blue Sodium Salt in various grades and quantities makes it accessible for a wide range of users, from academic research institutions to industrial laboratories. Professionals often seek out suppliers that can guarantee consistent quality, timely delivery, and competitive pricing. Manufacturers in China have become significant global providers of such laboratory chemicals, offering a reliable source for researchers worldwide. Whether you are performing delicate pH titrations or running complex gel electrophoresis experiments, selecting the right Bromophenol Blue Sodium Salt is essential for reproducible and accurate results. For those looking to buy this indispensable chemical, exploring options from established manufacturers can provide both quality assurance and cost-effectiveness.
