What is Perfluoroheptanoic acid?
Chemical properties
Perfluoroheptanoic acid is a white solid under ambient conditions, but it has a relatively low melting point (Huang, et al., 1987). In comparison, the C6 homologue, PFHxA, and other short-chain perfluorocarboxylic acids are volatile liquids (NICNAS, 2015a). The C8 homologue is also a solid under ambient conditions, although it has a relatively low sublimation temperature of 40°C (Kaiser, et al., 2010). Based on the properties of this long-chain homologue, solid PFHpA may sublime under ambient conditions.
The Uses of Perfluoroheptanoic acid
Perfluorinated compounds (PFCs) have been detected in many environmental matrixes, biota, and nonoccupationally exposed populations in China recently. Being a persistent environmental pollutant, it ca n accumulate in human tissues via various exposure routes. PFHA may interfere in a toxic fashion on the immune system, liver, development, and endocrine systems.
Perfluoroheptanoate (PFHpA, perfluoroheptanoic acid, perfluoro-n-heptanoic acid, tridecafluoro-1-heptanoic acid) is a seven-carbon compound in the perfluoroalkyl family of chemicals. Perfluoroheptanoate is used in stain- and grease-proof coatings on furniture, carpet, and food packaging.
Perfluoroheptanoate is the seven-carbon chemical that is structurally similar to the highly persistent and outlawed PFOA. Much like other perfluoroalkyls, PFHpA can persist in the environment.
The Uses of Perfluoroheptanoic acid
Perfluoroheptanoic acid is a important organic intermediate. It can be used in agrochemical, pharmaceutical and dyestuff field etc.
