Manufacturer 2,5-Dihydroxy-1,4-Dithiane CAS 40018-26-6
In the high-precision world of specialty flavor synthesis, pharmaceutical intermediates, and advanced material engineering, the choice of building blocks dictates the final yield and product purity. 2,5-Dihydroxy-1,4-dithiane (CAS40018-26-6 ), also commonly identified as 1,4-Dithiane-2,5-diol, is a pivotal sulfur-containing heterocyclic compound. It serves as the irreplaceable precursor for synthesizing premium meat flavor-enhancing aroma chemicals (such as 2-methyl-3-furanthiol) and highly sensitive photo-imaging reagents.
As a leading, certified source factory and direct chemical manufacturer, we don’t just broker ingredients—we control the molecular consistency from raw raw material to final container dispatch. This comprehensive guide outlines our technical standards, processing engineering, and scalable supply capabilities for B2B procurement teams worldwide.

Chemical Structure
Basic Info
Our factory-grade 2,5-Dihydroxy-1,4-dithiane is synthesized as a white to off-white crystalline powder. Because this molecule exists as a dimer of mercaptoacetaldehyde, maintaining its chemical stability and minimizing thermal degradation during storage and transit requires strict control over moisture and particle geometry.

Advanced Synthesis & Purification
he primary technical bottleneck for CAS 828-51-5 lies in controlling the odorous sulfur by-products and preventing premature polymerization or oxidation. Our R&D team has engineered a closed-loop, highly optimized synthesis route:
- Precision Atom-Economic Synthesis: We utilize a proprietary condensation method starting from high-grade raw materials, ensuring a highly selective dimerization process that limits structural isomers.
- Low-Temperature Vacuum Purification: Traditional crystallization often degrades sulfur-heterocycles. Our plant deploys automated multi-stage vacuum crystallization and low-temperature fluid bed drying to remove traces of free water and low-boiling sulfur impurities.
- Odors & Volatile Organic Compound (VOC) Control: By optimizing our scrubbing technology, we ensure our powder has highly predictable, clean reactive behavior when introduced into downstream flavor or pharmaceutical synthesis.

- B2B Packaging Formats: Standard packaging is available in 25kg fiber drums with double anti-static PE inner liners, or customized 1kg/5kg aluminum foil vacuum bags for pilot-scale R&D validation
FAQ
- Q1: What is the optimal storage condition for 2,5-Dihydroxy-1,4-dithiane?
A: Due to its potential to slowly dissociate or sensitive nature under high heat, we recommend storing the material in a cool, dry, and well-ventilated warehouse, ideally below 25°C (long-term bulk storage at 2-8°C is preferred for maximum shelf life up to 24 months). Keep containers tightly sealed under nitrogen blanketing if available. - Q2: Does your factory support custom adjustments to particle size?
A: Yes. We can modify our milling and screening parameters to provide ultra-fine powder or specific crystal granules depending on whether your process relies on rapid dissolution or dry powder blending. - Q3: What is the typical lead time for international container-load orders?
A: For standard stock quantities (under 2 tons), dispatch occurs within 7 working days. For custom large-scale campaigns (5+ tons), production lead times typically range from 14 to 21 days.
Factory Advantages & Regulatory Compliance
Sourcing directly from our plant grants your supply chain distinct commercial and technical advantages:
- Strict Isomer & Impurity Control: Unlike trading firms, we provide real-time batch-specific HPLC, GC-MS, and H-NMR spectra. Our material features a low ash profile and negligible heavy metal counts (≤10 ppm).
- EHS and Operational Safety: Our facility operates in full compliance with modern environmental protection and safety regulations, featuring advanced wastewater and exhaust gas treatment. This guarantees zero regulatory-driven supply shutdowns.
- Comprehensive Documentation Support: We provide complete technical packages including up-to-date Safety Data Sheets (SDS) matching GHS standards, Certificates of Analysis (COA), and full supply chain traceability documents.
