Luminol Sodium Salt is a crucial reagent in chemiluminescence analysis, easily soluble in water with high purity. It can be used as a luminescent substrate for metal ion and blood analysis, offering high sensitivity and selectivity. Its excellent solubility and stability make it advantageous in crime scene investigations, enabling accurate detection of biological samples.
In the field of chemistry, Luminol Sodium Salt is widely used in various analytical experiments as an important chemiluminescent reagent. Luminol Sodium Salt is the sodium salt form of Luminol, but it differs from Luminol in some aspects. For example, Luminol typically dissolves in alkaline solutions, while Luminol Sodium Salt is easily soluble in water. Many people know little about Luminol Sodium Salt, so let’s dive into more detail.
1. Basic Properties of Luminol Sodium Salt
Solubility
Luminol Sodium Salt, as the sodium salt form of Luminol, has distinct solubility features. It is highly water-soluble, with a solubility of up to 50 mg/mL, making it more convenient to use in aqueous solutions. In contrast, Luminol has poor solubility and generally requires organic solvents for dissolution. Therefore, Luminol Sodium Salt has greater application value in chemiluminescence analysis experiments.
Product Characteristics
Luminol Sodium Salt appears as a white or pale yellow powder with a high purity of 98% or more, presenting as a clean white powder. This high-purity product is stable and meets the needs of various chemiluminescence analyses. In terms of storage, Luminol Sodium Salt should be kept at room temperature and protected from light. Since it is sensitive to light and heat, long-term exposure to sunlight or high-temperature environments may lead to degradation in performance. Therefore, during storage and usage, it is advisable to avoid direct sunlight and high temperatures to maintain its stability.
2. Main Functions of Luminol Sodium Salt
Luminol Sodium Salt is widely used in scientific research and practical applications due to its chemiluminescent properties. Its main functions include:
As a Chemiluminescent Substrate
Like Luminol, Luminol Sodium Salt can be used as a chemiluminescent substrate. Chemiluminescence analysis is a highly sensitive and selective method with widespread applications in metal ion and blood analysis. Adding Luminol Sodium Salt as the luminescent substrate can produce a strong chemiluminescent reaction under specific conditions, enabling quantitative or qualitative analysis of target substances.
Metal Ion Analysis
Luminol Sodium Salt can react with metal ions, generating a chemiluminescent signal. By measuring the intensity of this signal, the concentration of metal ions can be quantified. This method features high sensitivity and selectivity, capable of detecting low concentrations of metal ions.
Blood Analysis
Luminol Sodium Salt can be used to detect peroxidase activity in blood. Peroxidase is an enzyme present in blood, and its activity is related to the freshness and source of the blood. By adding Luminol Sodium Salt as a luminescent substrate, the luminescent intensity of the blood sample can be observed, allowing the determination of peroxidase activity levels. This method is particularly useful in crime scene investigations for detecting traces of blood, iron, and hemoglobin.
3. Application Advantages of Luminol Sodium Salt
As a chemiluminescent substrate, Luminol Sodium Salt offers several advantages:
It can be used as a chemiluminescent substrate to detect peroxidase activity. By measuring the luminescent signal intensity, the peroxidase activity can be quantitatively evaluated, providing valuable reference data for experiments.
In chemical reactions, metal ions can catalyze oxidation reactions and generate signals. Luminol Sodium Salt can capture and amplify these signals, enabling highly sensitive detection of metal ions.
Compared to commonly used Luminol, Luminol Sodium Salt offers better solubility and stability. It dissolves in water and can be used under near-neutral pH conditions (close to a pH of 7), which is more aligned with the pH of blood. This makes Luminol Sodium Salt more advantageous in crime scene investigations, where it can more accurately detect the presence of blood and other biological samples.
