| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210-230 nm based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC-UV; identification by retention time matching and/or spiked reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of heavy metals after acid digestion; quantification by emission intensity at characteristic wavelengths relative to calibration standards. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anion on an anion-exchange column with conductivity detection; quantified using external calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and final ash weighing to determine inorganic residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Optical Rotation | [a]D | Measurement of specific rotation using sodium D-line light (589 nm) in solution to confirm chiral integrity and enantiomeric purity. |
| pH (1% aqueous solution) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed solid sample. |
| Microbial Limits | Membrane Filtration | Quantitative enumeration of aerobic bacteria, yeasts, and molds by filtration, membrane transfer to selective agar media, and colony counting after incubation. |

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?
