In the realm of biochemical research and diagnostic development, understanding the precise properties of key reagents is fundamental to successful outcomes. 3-Morpholinopropanesulfonic Acid (MOPS, CAS 1132-61-2) is one such critical component, widely utilized as a biological buffer. This article aims to provide a detailed overview of MOPS, covering its chemical properties, typical specifications, and common applications, along with guidance for procurement managers seeking to source this vital compound.

MOPS is a zwitterionic buffer that falls under the umbrella of Good's buffers, developed by Dr. Norman Good and colleagues. These buffers were specifically designed for biological research, offering advantages such as high water solubility, minimal interaction with metal ions, low UV absorbance, and stable buffering capacity in biologically relevant pH ranges. MOPS, with a pKa of 7.20 at 25°C, excels at maintaining pH stability between 6.5 and 7.9, making it invaluable for a variety of biochemical and cellular applications.

The typical specifications for high-quality MOPS include a minimum assay of 99%, ensuring a high degree of purity essential for sensitive assays. Its physical appearance is consistently described as a white crystalline powder. Other important parameters that researchers and manufacturers look for include a specific melting point range (e.g., 279-281°C), low water content, and minimal heavy metal contamination. When laboratories search to buy 3-Morpholinopropanesulfonic Acid, they often specify these purity levels and physical characteristics.

The primary applications of MOPS are in fields such as molecular biology, cell culture, and diagnostics. It is frequently incorporated into:

  • Biochemical diagnostic kits: MOPS helps maintain optimal pH for enzyme activity and reagent stability.
  • DNA/RNA extraction kits: It provides a stable pH environment crucial for preserving nucleic acid integrity during isolation.
  • PCR diagnostic kits: MOPS ensures the consistent pH required for efficient DNA amplification by thermostable polymerases.

For procurement managers, identifying a reliable 3-Morpholinopropanesulfonic Acid supplier is key. When evaluating suppliers, it's important to consider factors such as manufacturing certifications (e.g., GMP, SGS), consistency in product quality, and competitive pricing. Many procurement specialists will search for the 'price of MOPS buffer' from various sources to ensure they are getting the best value for their investment.
