Product Description:
Chromotropic acid sodium salt is widely used as a reagent in analytical chemistry for the detection and quantification of formaldehyde. It forms a colored complex with formaldehyde, which can be measured spectrophotometrically, making it a key component in environmental monitoring and industrial hygiene to assess formaldehyde levels in air, water, and other samples. Additionally, it is employed in the determination of other aldehydes and ketones in various chemical and biochemical analyses. Its application extends to the textile industry, where it is used in dyeing processes to improve color fastness and enhance the quality of dyed fabrics. In organic synthesis, it serves as a building block for the preparation of more complex compounds, particularly in the development of dyes and pigments.
