从India供应商批发进口Acid Red 151 Dyes — FOB条款

Sparrowings International supplies Acid Red 151 Dyes from Ahmedabad, Gujarat, India, with the chemical identified by CAS 6406-56-0 and EINECS 229-029-9. This monoazo acid dye carries the molecular formula C22H15N4NaO4S and is classified as a weak acid red BL type in standard dye nomenclature. The supplier presents the material as a powder-form product for leather, textile, and polyamide applications, with the Gujarat location placing it near India's major synthetic dye manufacturing corridor anchored in the Ahmedabad-Vadodara belt.

The dye structure features a single azo group with sulfonate functionality, conferring solubility in aqueous media and substantivity toward protein and polyamide substrates through ionic and hydrogen bonding mechanisms. Typical commercial specifications for this dye class include a pH-dependent absorption maximum near 510-520 nm in aqueous solution, with optimum exhaustion on nylon occurring at pH 4.5-6.0 using acetic or formic acid. Standard powder form specifications require 95% minimum through 250-micron sieve (typical), with bulk density ranging 0.5-0.8 g/cm3 depending on milling and standardisation. The weak acid designation indicates moderate to good levelling behaviour with somewhat lower wet fastness compared to super-milling or metal-complex variants.

Target buyers encompass leather tanneries requiring bright red shades for fashion and automotive upholstery leathers, textile commission dyers serving the Surat and Tiruppur garment clusters, and polyamide fibre producers. The supplier's Ahmedabad base offers logistical proximity to Mundra and Kandla ports for export shipment, as well as domestic road and rail connectivity to northern and western Indian industrial zones. Pricing, minimum order quantities, and standard lead times are not disclosed in the available data and must be confirmed through direct supplier enquiry.

Sparrowings International operates from D-101, Maruti Homes, Opposite Shreenath Elegance, Nana Chiloda, Ahmedabad 382330, Gujarat, India. The supplier holds a harbor trust tier but shows a zero percent response rate with no recorded average response hours, indicating either a new listing or inactive account status. The company identifies itself as Sparrowings brand and markets acid and azoic dye products for leather, textile, and polyamide end-uses, positioning within Gujarat's established chemical manufacturing ecosystem.

The supplier profile contains no information about establishment year, production scale, number of employees, annual turnover, quality certifications, export experience, or named customers. No manufacturing facility details, R&D capabilities, or environmental compliance statements are provided. Buyers should independently verify operational status, production capacity, and quality management systems before advancing beyond initial enquiry, particularly given the lack of response history that would demonstrate communication reliability.
