An in-depth analysis of chemical properties, synthesis pathways, industrial optimization, and global market dynamics for CAS 629-19-6.
Dipropyl disulfide (CAS 629-19-6), also structurally identified as propyl disulfide or 4,5-dithiaoctane, is a key organosulfur compound characterized by its linear disulfide linkage bridging two propyl organic moieties. Operating under the molecular formula C6H14S2, this volatile compound displays a distinct pungent, garlic-like sulfurous odor profile, rendering it invaluable across flavor chemistry, agricultural formulation, and specialized organic synthesis.

Manufacturing high-purity Dipropyl disulfide within China requires rigorous controls over oxidation kinetics and sulfur stoichiometry to prevent undesirable trisulfide or monosulfide side-products. Modern industrial synthesis primarily leverages the catalytic oxidation of 1-propanethiol using optimized peroxide or atmospheric oxygen systems under phase-transfer catalysis.
Key advantages of modern Chinese chemical manufacturing infrastructures include:
Dipropyl disulfide acts as a fundamental aromatic constituent used by global flavor houses to recreate authentic allium profiles (garlic, onion, shallot, and leek). Its low olfactory threshold allows precise dosage in savory seasonings, ready-to-eat meals, and bouillon bases.
In modern bio-pesticide and soil fumigant formulations, Dipropyl disulfide exhibits strong nematicidal and anti-fungal properties. As regulatory bodies restrict traditional halogenated fumigants, organosulfur derivatives provide a biodegradable, environmentally sound alternative.
In animal nutrition, controlled concentrations of pure dipropyl disulfide serve as key flavor enhancers for feline and canine nutritional digest formulations, mimicking natural cooked meat volatiles.

Key technical, commercial, and regulatory guidance for international buyers purchasing Dipropyl disulfide.
Our standard industrial grade Dipropyl disulfide maintains a minimum purity of 98.0% determined by Gas Chromatography (GC). For specialized flavor formulation or high-sensitivity organic synthesis, we offer a refined grade reaching ≥ 99.0% purity with residual propanethiol strictly capped below 0.05%.
Due to its characteristic odor profile and liquid properties, Dipropyl disulfide is routinely packaged in UN-approved 200L fluorinated HD-PE drums, epoxy-lined steel drums (200kg net), or 1000kg IBC tanks. For bulk oceanic delivery, ISO tank shipments (up to 20 metric tons) are available under full hazardous material packaging compliance (UN 1993/Class 3/PG III as applicable).
Yes, JIMPOCHEM provides comprehensive support for European buyers, including REACH OR (Only Representative) coverage, ISO 9001/14001 certification dossiers, Safety Data Sheets (SDS) matching GHS standards in multiple languages, and batch-specific Certificates of Analysis (CoA).
Absolutely. Our R&D technical team specializes in organosulfur chemistry, including asymmetrical disulfides, diallyl trisulfide, and related thiol derivatives. We offer custom synthesis scaling from kilogram pilot batches up to multi-ton commercial production runs.
Dipropyl disulfide should be stored in tightly sealed containers in a cool, well-ventilated area away from direct sunlight, heat sources, and strong oxidizing agents. Under recommended sealed storage conditions (below 25°C), the product retains full shelf stability for 24 months from the date of manufacture.
