Its molecular formula is C32H27N5Na2O8S2, indicating a complex structure designed for high affinity to cellulose-based substrates. The product is marketed for use in ink, paper, and textile dyeing applications requiring intense violet tones.
The dye is formulated to deliver consistent coloration in aqueous systems with minimal sedimentation. It is typically classified as a medium-fast dye for paper and inkjet applications, with moderate lightfastness and washfastness.

Verify the molecular formula and CAS number on the supplier’s certificate of analysis against published chemical databases. Confirm that the dye is free from heavy metals such as lead, arsenic, and chromium, especially if used in paper for children’s products. Request a sample for shade matching under daylight and artificial lighting conditions to ensure consistency.
Lead time is typically 12 to 18 days from order confirmation, with FOB Ahmedabad as the standard term. Payment is commonly made via LC or wire transfer after shipment. Buyers should confirm whether the packaging is moisture-resistant and if the containers are labeled with batch number, production date, and hazard symbols. Ask for a copy of the export invoice format used for customs clearance.
Perform incoming inspection for color consistency, moisture content, and packaging integrity. Use a spectrophotometer to compare the sample against the approved standard. Retain a sealed sample from each shipment for quality audits. Ensure the supplier provides a GHS-compliant SDS and confirm that the product is not subject to import restrictions in your country under REACH or similar regulations.
