TMp

TMP is an acronym used in several distinct fields, referring to different terms depending on the context. Notable meanings appear in chemistry, fuel science, computing, and biology.

In chemistry and materials science, TMP most often denotes trimethylolpropane, a triol widely used as a crosslinking agent in polyurethane resins, coatings, and foams. In fuel chemistry, TMP can refer to 2,2,4-trimethylpentane, a hydrocarbon also known as iso-octane, which serves as a reference component in octane rating scales and gasoline formulations.

In computing, TMP commonly stands for temporary storage or work areas. The TMP environment variable and the TMP directory (often /tmp on Unix-like systems or C:\Windows\Temp on Windows) are used for intermediate or transient data created by software during processing.

In biology and biochemistry, TMP may refer to transmembrane protein, a protein that spans a cellular membrane, or thymidine monophosphate, a nucleotide involved in DNA and RNA metabolism.

TMP can also appear as an acronym in other specialized domains, where its meaning is defined by the relevant discipline or organization. In practice, the exact interpretation of TMP is typically clarified by context, and sources in a given article should specify which TMP is being discussed to avoid ambiguity.
