Basic Information and Parameters

The product we are discussing here is 2,6-pyridinedicarboxylic acid with the CAS number 499 - 83 - 2. It is available from factory supply at a good price. 2,6 - pyridinedicarboxylic acid, also known as dipicolinic acid, has a molecular formula of C₇H₅NO₄ and a molecular weight of approximately 167.12 g/mol. It appears as a white to off - white crystalline powder.

The melting point of 2,6 - pyridinedicarboxylic acid is around 257 - 259 °C. It has a certain solubility in water and is slightly soluble in common organic solvents such as ethanol and acetone. The purity of our factory - supplied product can usually reach over 98%, ensuring high - quality performance in various applications.

Uses of the Product

2,6 - pyridinedicarboxylic acid has a wide range of applications in different fields. In the field of coordination chemistry, it is a commonly used ligand. It can form stable coordination compounds with various metal ions, such as transition metal ions like iron, copper, and nickel. These coordination compounds have potential applications in catalysis, as they can enhance the reaction rate and selectivity of some chemical reactions.

In the biological field, dipicolinic acid is an important component in bacterial endospores. It helps the spores resist harsh environmental conditions, such as high temperatures, dryness, and chemical disinfectants. Therefore, it can be used in research related to spore - forming bacteria and in the development of antibacterial agents.

It also has applications in the analytical field. Due to its ability to form colored complexes with certain metal ions, it can be used as a reagent for detecting and quantifying metal ions in samples, which is very important for environmental monitoring and quality control in the chemical industry.

How to Use the Product

When using 2,6 - pyridinedicarboxylic acid, appropriate safety precautions should be taken. Wear protective gloves, goggles, and a lab coat to avoid direct contact with the skin, eyes, and inhalation of dust.

If you need to dissolve it, start with a small amount of the appropriate solvent, such as water or a specific organic solvent depending on your application. Stir gently until it is completely dissolved. When using it as a ligand in coordination chemistry, add it to the reaction system in an appropriate molar ratio according to the design of your experiment. Make sure the reaction conditions, such as temperature, pH value, and reaction time, are well - controlled to ensure the formation of the desired coordination compounds.

In the analytical field, prepare standard solutions of known concentrations of the metal ions and add a certain amount of 2,6 - pyridinedicarboxylic acid. Then, measure the absorbance or other relevant physical and chemical properties at specific wavelengths to establish a calibration curve for quantitative analysis.

Usage Case Studies

Case 1: Catalytic Reaction in Organic Synthesis

A research group was trying to optimize the synthesis of a certain organic compound. They used a copper complex with 2,6 - pyridinedicarboxylic acid as a catalyst. In a reaction system of a certain esterification reaction, they added the catalyst in a molar ratio of 1:100 (catalyst: reactant). Under the reaction conditions of 80 °C and a reaction time of 4 hours, the conversion rate of the reactants increased from 60% (without catalyst) to over 90%. The selectivity of the target product also improved significantly, reducing the formation of by - products.

Case 2: Detection of Metal Ions in Environmental Samples

An environmental monitoring laboratory needed to detect the concentration of iron ions in a water sample. They prepared a series of standard solutions of iron ions with different concentrations and added a fixed amount of 2,6 - pyridinedicarboxylic acid. By measuring the absorbance of these solutions at a wavelength of 520 nm, they established a calibration curve. Then, they measured the absorbance of the water sample and calculated the concentration of iron ions in the sample through the calibration curve. The results showed that the method was accurate and sensitive, with a detection limit of 0.01 mg/L.
