View Product DetailsAn in-depth biochemical overview of Androsta-1,4-diene-3,17-dione (ADD), its biological role as a vital synthesis precursor, and our multi-step biotechnological evolution roadmap.
Androsta-1,4-diene-3,17-dione (CAS 897-06-3), commonly referenced as 1,4-diene-3,17-dione or ADD, features a 4-ring cyclopentanoperhydrophenanthrene core with conjugated double bonds at positions C1-C2 and C4-C5, and ketone moieties at C3 and C17. This unique structural unsaturation confers exceptional reactivity for aromatase-driven reactions and downstream functionalization.
Moving away from environmentally taxing chemical chromium degradation, our facility pioneers microbial cleavage of natural phytosterols (derived from non-GMO soy and pine sterols) utilizing engineered Mycobacterium strains. This green chemistry path guarantees zero heavy metal toxicity and sharp regio-selectivity.
Our 2026–2030 technology roadmap focuses on continuous crystallization, enzymatic immobilization, and automated closed-loop HPLC monitoring. Transitioning to enzymatic dehydrogenation minimizes solvent consumption by 42% while narrowing polymorph variance for critical downstream API contracts.
Enterprise chemical procurement teams navigate shifting environmental mandates, price volatility, and regulatory audits. Here is how our scaled production solves systematic vulnerability.
| Procurement Dimension | Legacy Sourcing Challenges | Our Factory 4.0 Verified Solution |
|---|---|---|
| Batch Consistency | Fluctuating residual sterols, non-uniform recrystallization, and uncharacterized C1/C2 side degradation. | Closed-loop spectrophotometric crystallization ensuring batch-to-batch HPLC purity variance < 0.2%. |
| Supply Chain Continuity | Fragmented small workshops vulnerable to environmental shut-downs and energy curtailments. | Eco-audited industrial park presence with dual dedicated power grids and 12-month raw biomass inventory. |
| Audit Integrity & Data | Hand-written logs, missing impurity profiles, and inadequate electronic spectral archives. | Full 21 CFR Part 11 electronic data retention, verified mass spectrometry (LC-MS), and proton NMR (1H-NMR). |
| Logistics Clearance | Customs seizures caused by incorrect HS coding, missing TSCA/REACH declarations, or poor labeling. | Pre-cleared DDP multi-hub logistics with complete analytical dossiers, UN-certified air/sea drums, and customs guarantees. |
Operating from Hebei's advanced industrial chemical corridors, our infrastructure integrates SCADA-driven bioprocessing with multi-stage analytical governance.
Our factory houses 60,000L deep-tank aerobic fermenters equipped with real-time dissolved oxygen (DO), pH, and carbon-source automated feed loops. Following bioconversion, crude streams pass through continuous centrifugation, non-polar macroporous resin adsorption, and ultrasonic-assisted recrystallization. This end-to-end integration eliminates transport intermediaries, prevents cross-contamination, and yields pure, snow-white crystalline 1,4-diene-3,17-dione powder.
Every lot undergoes rigorous analytical screening: Shimadzu HPLC purity assay, residual solvent headspace GC, Agilent ICP-MS heavy metal testing, and Karl Fischer moisture titration. Documentation is generated live at the instrument level.
Managing global chemical importation requires meticulous regulatory alignment. We ensure your orders fulfill all national customs and environmental standards without friction.
We supply exhaustive Technical Data Sheets (TDS), 16-section GHS-compliant Safety Data Sheets (SDS), Certificates of Origin (COO), and formal Declarations of Non-BSE/TSE status. Our regulatory unit handles REACH dossiers, US TSCA notices, and localized customs classifications.
Mitigate clearance risk with our dedicated chemical forwarding corridors. We maintain bonded warehousing partners across North America, the European Union, and Southeast Asia, guaranteeing rapid dispatch, zero tax surprises, and end-to-end tracking to your manufacturing door.
Dedicated English-speaking technical sales managers and chemical engineers assist throughout the vendor qualification process, coordinating audit questionnaires, pilot scale sampling, batch reservations, and custom bulk pack sizes.
Enterprise chemical procurement leaders balance supply stability, total landed cost, and multi-tier quality guarantees. Our contractual workflows are structured to meet strict corporate benchmarks.
Direct-from-factory pricing structures insulate partners from broker markups. We offer indexed long-term supply agreements (LTA) and quarterly price locks to help budget managers hedge against global commodity fluctuations.
Standard packaging includes double pharmaceutical-grade polyethylene linings inside UN-approved 25kg fiber drums. Micro-pulverization, custom mesh sizing (80 to 200 mesh), and smaller R&D batch aliquot options are available upon specification.
We welcome third-party technical audits (SGS, Intertek) and conduct secure virtual facility walkthroughs, granting technical teams transparent insight into our fermentation floors, QC instrumentation, and raw material warehouses.
Find direct answers to the most common chemical, logistical, and commercial inquiries regarding 1,4 diene-3-17b-dione procurement.
Androsta-1,4-diene-3,17-dione (ADD) serves as a primary steroid precursor used for downstream multi-step chemical synthesis. It is an indispensable intermediate for producing Boldenone derivatives, Exemestane (an aromatase inhibitor used in oncology), and other modified steroid compounds that require an unsaturated A-ring.
Following fermentation, our multistep downstream processing includes solvent extraction, decolorization with activated carbon, and fine filtration through sub-micron sterile ceramic membranes. Heavy metals are quantified via ICP-MS to ensure levels remain well below 10 ppm, adhering to USP/EP pharmacopeial impurity guidelines.
For standard evaluation and pilot testing, our MOQ starts at 1 kg. For commercial contract orders, standard batch allocations range from 25 kg to multi-metric-ton commitments. In-stock lots dispatch within 48 to 72 hours, while custom particle milling orders typically ship within 7 to 10 business days.
Yes. We support contract packaging and neutral labeling for domestic and international distributors. All outer drum labeling can be customized with your internal batch nomenclature, barcodes, and specified hazard identifiers, while preserving lot traceability to the master manufacturer COA.
