从India供应商批发进口Acid Bright Red 2b — FOB条款

Acid Bright Red 2B is an azo-based acid dye supplied by Lepid Life Sciences Pvt Ltd from their facility in Rajasthan, India, with material originating from China. The product presents as a red powder (molecular weight 551.29) designed primarily for wool dyeing applications, with secondary use on silk and in direct printing for wool-silk blended fabrics. The dye's chromophore consists of a monoazo structure with sulfonic acid groups, conferring water solubility under acidic conditions and substantivity for protein fibres through ionic and hydrogen bonding mechanisms. Its bright red shade profile positions it in the colour space between Acid Red 1 and Acid Red 14, offering moderate to good leveling properties typical of this dye class.

The molecular weight of 551.29 indicates a relatively compact dye structure with favourable diffusion characteristics into wool fibres at 95-100°C. Standard acid dyeing practice employs sulfuric acid, formic acid, or ammonium sulfate to maintain pH 3.0-5.5 for optimal exhaustion and levelness. The dye's affinity for leather (noted in the source description) derives from similar proteinaceous substrate chemistry, though metal content and pH sensitivity must be controlled to prevent bronzing or shade dullness. Commercial grades typically contain 70-80% active dye (typical) with sodium sulfate or dextrin standardisers, and moisture content below 5% to prevent caking during storage.

Target buyers for Acid Bright Red 2B include woolen mills, carpet manufacturers, silk weavers, and leather finishers seeking economical bright red shades. The 25 kg fibre drum packaging (standard for this product category) suits medium-volume dye houses with controlled humidity storage. Lepid Life Sciences does not list MOQ, pricing, or lead time in available data, nor do they confirm local stockholding versus direct China sourcing. Buyers should verify whether the Rajasthan facility performs repackaging, quality control testing, or holds inventory, as this affects responsiveness and batch consistency for repeat orders.

Lepid Life Sciences Pvt Ltd operates from G-840, Khushkhera Industrial Area, Tehsil Tijara, District Alwar, Rajasthan 301707, India. The Khushkhera location sits in the Delhi-Mumbai Industrial Corridor with access to Bhiwadi manufacturing cluster infrastructure. The company carries a 'harbor' trust tier with zero recorded response rate and no response time data, suggesting limited platform engagement or a newly established listing profile. Their source description explicitly states Chinese origin for Acid Bright Red 2B, indicating trading or import-distribution activity rather than domestic manufacturing.

The supplier profile lacks stated annual turnover, employee count, quality certifications, or manufacturing capabilities. No ISO, GMP, or environmental compliance credentials are mentioned. The Rajasthan facility's role, whether warehousing, repackaging, or quality testing, is undefined in available data. Lepid Life Sciences does not list client references, export experience, or additional product portfolio depth. Buyers must independently verify operational scale, financial stability, and technical competency before establishing credit terms or volume commitments.
