CAS 2379-77-3: Vat Red 32

Description:Vat Red 32, with the CAS number 2379-77-3, is a synthetic organic dye belonging to the vat dye class, which is known for its excellent lightfastness and washfastness properties. This dye is primarily used in the textile industry for dyeing cotton and other cellulose fibers, providing vibrant red hues. Vat dyes are characterized by their insolubility in water in their original form, requiring a reduction process to convert them into a soluble form for application. Once applied to the fabric, they are oxidized back to their insoluble state, resulting in a durable bond with the fiber. Vat Red 32 is also noted for its stability under various environmental conditions, making it suitable for use in a range of applications beyond textiles, including plastics and paper. However, as with many synthetic dyes, there are environmental and health considerations associated with its use, necessitating careful handling and adherence to safety regulations during manufacturing and application processes.
