Import Acid Orange 142 — Buy in wholesale FOB from Supplier in India

Acid Orange 142 is a monoazo acid dye supplied as a powder by Sparrowings International from Gujarat, India, with the chemical name Acid Orange MRL and molecular formula C16H12N5NaO7S. Its CAS number is 61901-39-1, confirming it as a sodium salt of an azo dye designed for substantivity to proteinaceous and polyamide fibres through ionic bonding. The product is offered in powder form, which is the standard physical state for industrial acid dye handling and dosing.

The dye structure contains a sulfonic acid group (the sodium salt, -SO3Na) that confers water solubility and affinity for cationic sites on nylon, wool, and leather substrates. Typical commercial Acid Orange 142 exhibits a pH-dependent stability profile, with optimal application in the acidic pH range of 4.5 to 6.0 for polyamide substrates. Standard commercial grades carry a minimum dye content of 80 percent, with the balance comprising sodium chloride, sodium sulfate, or dispersing agents to standardise strength and flow properties.

Primary applications span leather dyestuffs, textile dyestuffs on wool and silk, and polyamide coloration including carpets and apparel fabrics. Buyers are typically tanneries, textile commission dyers, and nylon fibre producers seeking consistent batch-to-batch shade reproduction. Trade terms, minimum order quantities, and lead times should be confirmed directly with Sparrowings International, as these are not stated in the listing.

The company holds a Harbor trust tier and has a response rate of 0.00 percent with zero recorded average response hours, which may indicate limited engagement through the platform or a new listing status. The supplier's104 listing presents Acid Orange 142 under the Sparrowings brand name, suggesting proprietary sourcing or formulation control rather than pure trading.

The listing provides only the source description as profile material, with no stated manufacturing certifications, export licence numbers, or quality management accreditations. Buyers should verify whether Sparrowings International operates as a manufacturer, formulator, or distributor, and whether batch analysis certificates or safety data sheets are available on request. The Gujarat location places the supplier within India's principal chemical manufacturing belt, though this geographic proximity to feedstocks does not independently confirm production capability.
