Industrial Applications of Homocystine
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Serves as a biomarker in metabolic studies for diagnosis and monitoring of diseases associated with homocysteine metabolism | Plasma or urine homocysteine levels are quantified in clinical testing using high-performance liquid chromatography (HPLC) or mass spectrometry |
| Biochemical Research | Used to investigate protein cross-linking, oxidative stress, and amino acid metabolic pathways | Applied in laboratory settings as a reference standard or substrate in in vitro enzymatic assays or cell culture studies |
| Nutrition & Health | Supports assessment of vitamin B6, B12, and folate deficiency status | Nutritional status is evaluated through intervention trials combined with blood homocysteine concentration analysis |
Manufacturing Quality Control of Homocystine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (High Cystine Content) | Acid-Base Titration with NaOH | Quantifies free carboxylic acid groups after dissolution in HCl and back-titration with standardized NaOH. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Reaction with thioacetamide under controlled pH to form colored metal sulfides, compared visually or spectrophotometrically. |
| Loss on Drying | Gravimetric Thermogravimetry | Measures mass loss after drying at 105 C for 2 hours; reflects volatile impurities and residual moisture. |
| Residue on Ignition | Gravimetric Ashing | Determines inorganic ash content by ignition at 600 C until constant weight is achieved. |
| Chloride Impurity | Argentometric Titration (Mohr Method) | Titration with AgNO3 using K2CrO4 indicator; forms red Ag2CrO4 endpoint after all Cl- is precipitated as AgCl. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| Related Substances | Reverse-Phase HPLC with UV Detection | Separation on C18 column using gradient mobile phase; detection at 210 nm based on UV absorbance differences. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light; confirms chiral purity and identity of L,L-cystine. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines pH of 1% w/v aqueous suspension using calibrated pH electrode and buffer reference. |
| Iron Impurity | UV-Vis Spectrophotometry (1,10-Phenanthroline Method) | Forms orange-red Fe(II)-phenanthroline complex; quantified by absorbance at 510 nm. |
| Arsenic | Silver Diethyldithiocarbamate (SDDC) Method | Arsine gas generated from sample reacts with SDDC to yield red-colored complex measured at 540 nm. |
| Microbial Limits | Membrane Filtration and Plate Count | Sample filtered through membrane, then placed on TSA and SDA agar plates; colonies counted after incubation. |

Industrial Homocystine Procurement FAQ
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?
