Import Acid Red 151 - Red F2r — Buy in Bulk from Supplier in India

Acid Red 151, also known as Red F2R, is a monoazo acid dye with the molecular formula C22H15N4NaO4S and CAS number 6406-56-0, supplied by Karsandas Mavji from Mumbai, Maharashtra. This dye belongs to the acid dye class used for protein and polyamide fibres, presenting as a red powder with good water solubility due to its sulfonic acid sodium salt structure. The supplier formulates this product using industrial-grade acids and coupling components, offering it in multiple packaging configurations to suit varied industrial requirements.

The dye chemistry relies on an azo chromophore (-N=N-) that produces a bright red shade with good levelling properties on wool and nylon substrates. Typical commercial grades of Acid Red 151 show a dye content of 80% minimum (standard), with moisture content at 5% maximum and water-insoluble matter below 1% (typical). The product exhibits good light fastness ratings of 4-5 on the ISO 105-B02 scale and moderate washing fastness of 3-4, though exact fastness values for this batch should be confirmed with the supplier. Standard packaging for acid dyes in the Indian market includes 25 kg fibre drums or HDPE bags with inner polyethylene liners to prevent moisture ingress during monsoon transit conditions.

Primary applications for Acid Red 151 span wool and nylon textile dyeing, silk colouring, paper tinting, leather finishing, and ink formulations. The dye finds particular use in carpet and hosiery sectors where bright shades and moderate production costs align with market demands. Buyers typically include textile commission dyers, leather tanning operations, and specialty ink manufacturers across South Asia and export markets.
