Heptane (CAS# 142-82-5)
n-Heptane, also known as N-heptane or CH3-[CH2]5-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Straight-Chain AlkaneHeptane or n-heptane is the straight-chain alkane with the chemical formula H₃C(CH₂)₅CH₃ or C₇H₁₆, and is one of the main components of gasoline. Synonyms & Trade Names Heptane, normal-Heptane CAS No. 142-82-5 RTECS No. MI7700000. DOT ID & Guide. 1206 128. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale.
Junyuan Petroleum Group’s n-Heptane, 99%, CAS No. 142-82-5, medical grade of n-Heptane and its applications: It is widely used for the production of rubber and plastic,painting material, dyestuff, printing ink, adhesive, medicine, agricultural chemicals, food additives, feed additive, flavor spices, cosmetics.
Lab-grade chemicals, because of their low cost and good chemical purity, are used widely in educational applications, such as teaching laboratories at both the secondary school and college levels; however, lab-grade chemicals would not be appropriate for use in the quality control laboratory of a pharmaceutical or medical device.
Heptane is a flammable, volatile, organic, straight-chain alkane of seven carbon atoms. Available in a range of quantities, purities, and reagent grades, heptane is a commonly used non-polar solvent and a key component in gasoline. Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of isooctane in heptane and is listed on pumps for gasoline dispensed globally. Any of several isomeric, volatile, colorless, highly flammable liquid hydrocarbons, C7H16, obtained in the fractional distillation of petroleum and used as solvents.
The straight-chain isomer is also used as a standard in determining octane ratings and as an anesthetic. Thermodynamic properties of standard n-heptane from 155 to 270K and of 2,2-dichloropropane from 135 to 270K, J. Chem. Thermodynam., 1972, 4, 773-782.

Acetone and n-Heptane are widely applied in pharmaceutical industry as benign solvents and are observed in the wastewater.Because acetone and n-hexane can form an azeotropic mixture, it is impossible to recover acetone and n-Heptane with high purity from the wastewater using conventional distillation.
High purity n-Heptane is produced from crude oil through precision refining and distillation that is used in the measurement of octane rating for fuels. It is also used for the purification of pharmaceutical products and other synthetic organics.
n-Heptane is widely applied in laboratories as a totally non-polar solvent. Usage Statement . Unless specified otherwise, MP Biomedical’s products are for research or further manufacturing use only, not for direct human use. For more information, please contact our customer service department.
It is written as n-Heptane when the polymer is unbranched, hence depicts a straight-chained structure. The presence of heptane in paintings and coatings forces the consumption of oxygen in microorganisms, which is a vital element in metal corrosion.
