1.Basic Information
1) Reduced indanone dihydrate is an organic compound belonging to indanone derivatives. Its chemical formula is C18H14O8, molecular weight is 358.3, and CAS number is 5950-69-6.
2)In terms of physical properties, the product is a prismatic crystal with a slightly pinkish crystalline powder appearance. It is sensitive to light and loses its crystalline water at 100 ℃, turns reddish brown at around 200 ℃, and decomposes at around 249-254 ℃.
3)In terms of solubility, it is insoluble in water but soluble in ethylene glycol monomethyl ether. It is worth noting that it appears dark red when dissolved in sodium carbonate aqueous solution, dark blue when dissolved in sodium hydroxide solution, dark purple when reacting with ammonia, and blue when reacting with amino acids. These characteristic color reactions are the basis of its analytical applications.
4)Structural formula:
2.Core purpose and working principle
The core use of reducing indene trihydrate is as a synergistic agent for indene trihydrate, used for the photometric determination of amino acids.
The indene ketone reaction is a classic method for detecting amino acids and peptides. In this reaction, reduced indanone dihydrate is used as a synergist to enhance the sensitivity of the colorimetric reaction, helping researchers to more accurately determine the concentration of amino acids in the sample. This characteristic has long been applied in traditional amino acid analysis techniques such as Stein Moore Chromatography.
3.Correct storage method
Given that its chemical stability is influenced by the environment, the correct storage method is crucial for maintaining the activity of the reagent and extending its shelf life.
1）Storage conditions: Keep away from light and seal in a cool and dry place. It is recommended to store at room temperature.
2）Shelf life: The shelf life provided by different suppliers varies from 1 year to 3 years, and should be based on the actual product label.
In addition, the reagent should avoid contact with oxidants and ensure good ventilation during use
4.Safety precautions
Although the reduction of indanone dihydrate is commonly used in the laboratory, attention should still be paid to its safety risks.
1）Toxicity: This substance has certain toxicity to the human body. The data shows that the median lethal dose (LD50) for intravenous injection in mice is 320mg/kg.
2）Irritation: Contact with eyes may cause mild irritation.
3）Suggestion for handling: During operation, laboratory safety regulations should be followed to avoid direct contact with skin and eyes. After use, waste should be properly disposed of to avoid polluting the environment
5.Specific analysis of storage conditions and stability
1）Regarding storage conditions, multiple suppliers have explicitly stated that the product should be kept away from light and sealed in a cool and dry place. Some suppliers suggest storing at room temperature (RT).
2）Regarding stability, the product is relatively stable at room temperature and pressure, but sensitive to light. Its decomposition temperature is around 250 ℃, and it does not decompose in daily storage environments.
3）The labeling of the validity period varies among different suppliers. For example, Biyun Tian Biotechnology is labeled as 3 years, AlphaBiotech is labeled as 2 years, and some suppliers are labeled as 1 year. It is recommended to refer to the actual label of the product.
