Here is a detailed English-only explanation of the various aliases for n-Heptane in international trade:
1. n-Heptane
The standard IUPAC name, referring specifically to the straight-chain (unbranched) isomer of heptane (C₇H₁₆). It is used as the zero-point reference for octane rating in gasoline testing.
2. Heptane
A general term that may refer to n-Heptane but can also include other heptane isomers (e.g., 2-methylhexane, 3-methylhexane). In industrial contexts, it often implies the dominant straight-chain form.
3. Dipropylmethane
A structural alias, derived from its molecular configuration: two propyl groups (C₃H₇) attached to a central methylene (CH₂) unit.
4. Heptyl hydride
A systematic derivative name, emphasizing its classification as a saturated hydrocarbon (alkane) where hydrogen atoms are bonded to a heptyl chain.
5. Normal heptane
Explicitly denotes the linear (non-branched) structure, distinguishing it from branched isomers like isoheptane.
6. n-C7 (Industrial shorthand)
Common in petrochemical trade, where "n" stands for normal (straight-chain) and "C7" indicates 7 carbon atoms.

Septane – A rare historical term, now largely obsolete.
Usage Notes
n-Heptane is the most precise term in chemical commerce, while Heptane may sometimes include mixed isomers.
Dipropylmethane and Heptyl hydride are more common in technical literature than in trade.
n-C7 is frequently used in oil refining and bulk chemical transactions811.
For safety and regulatory documents, n-Heptane (UN 1206) is the standard designation
