| Industry | Application | Process |
|---|---|---|
| Dyeing and Printing | As a reactive dye for dyeing cotton, viscose, and other fibers | Bonded covalently to fibers via azo linkage |
| Chemical Manufacturing | Intermediate for synthesizing other organic compounds | Produced via nitration, diazotization, and coupling reactions |
| Ink Manufacturing | Blue pigment or dye component in printing inks | Formulated into ink systems with resins and solvents |
| Paper Manufacturing | Used for paper dyeing and coating | Applied in combination with fillers and binders to enhance color performance |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Dye Content) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max in standardized solvent and calculates concentration using Beer-Lambert law and certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 C) | Residue after high-temperature incineration is weighed to determine non-volatile inorganic impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements in acid-digested sample. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ion concentration by titration with silver nitrate using silver indicator electrode. |
| pH of 1% Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in aqueous dispersion using calibrated glass electrode and pH meter. |
| Water Solubility | Gravimetric Filtration | Compares mass of undissolved residue after dissolution, filtration, and drying under controlled conditions. |
| Substantivity (on Cotton) | Spectrophotometric Dye Uptake | Quantifies dye adsorption onto cotton fabric by comparing UV-Vis absorbance of spent vs. initial dye bath. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Particle Size Distribution | Laser Diffraction | Measures scattered laser light intensity as function of angle to calculate volume-based particle size distribution. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of powder in calibrated cylinder. |
| Thermal Stability (Onset Decomposition Temp) | TGA | Monitors mass loss vs. temperature under controlled heating rate to identify decomposition onset. |

1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
