Does CAS 34464-38-5 specifically correspond to isodecane?

Yes. CAS 34464-38-5 is assigned to isodecane, representing branched C₁₀ hydrocarbon isomers.

Is isodecane under this CAS number a single pure isomer?

No. The CAS definition refers to a material composed predominantly of branched decane isomers rather than a single defined structural isomer.

Isodecane CAS 34464-38-5

Isodecane, chemically characterized as a mixture of branched-chain decane isomers, is a volatile liquid hydrocarbon widely utilized as a high-purity non-polar solvent. Frequently referenced in technical documentation as Decane branched or C10 iso-alkane, this fluid functions as a fast-evaporating carrier in coating formulations, a viscosity regulator in industrial adhesives, and a cleaning agent in precision degreasing applications. We offer bulk supply of this industrial solvent with competitive factory pricing, customized specifications for flash point and distillation ranges, and comprehensive regulatory documentation including MSDS, TDS, COA.

Application Areas

Solvent: Isodecane has good solubility and volatility, and can be used as a solvent for the production of pesticides (herbicides, insecticides, ant repellents, etc.), glass bottle protectants, automotive and household fragrances, automotive protective wax, machine tool wax, etc. In addition, it can also be used for household appliance metal parts, LCD filters, and cleaning agents before electroplating.
Organic synthesis: Isodecane can be used as a raw material for organic synthesis to prepare some complex organic compounds.
Fuel research: Isodecane can be used in fuel research as a fuel additive or model compound to study the performance and combustion characteristics of fuels.

Storage conditions

Storage environment: It should be stored in a cool, well ventilated place, preferably outdoors or separately stored. The storage temperature should not be too high, generally kept at room temperature, while avoiding direct sunlight.
Container selection: Oil tankers, railway tank trucks, tank cars, barrels, etc. can be used as storage containers, and the containers should be kept sealed to prevent the volatilization of isodecane.
Avoid mixed storage: Isodecane should be stored separately from oxidants to prevent chemical reactions.

Safety precautions

Risk of combustion and explosion: flash point 38.3 ° C, vapor pressure 2.3mmHg (25 ° C), keep away from sources of fire and high temperatures.
Health hazards: May cause skin or respiratory irritation, it is recommended to wear protective gloves and goggles during operation.
Transportation and handling: must comply with hazardous material transportation regulations to avoid leakage
