• The first report of soluble PAHs of Mukundpura (MK) CM2.0 Chondrite.
• The composition of PAHs in MK is similar to PAHs reported in other CM2.0 Chondrites.
• The presence of alkylated PAHs in MK indicates appreciable aqueous alteration on its parent body.”

“Soluble polyaromatic hydrocarbons (PAHs) have been measured in Mukundpura (MK) CM2 carbonaceous chondrite using Gas Chromatography-Mass Spectrometry (GC-MS). The data show high yields of PAHs with the presence of 2, 3, and 4 ring polyaromatic hydrocarbons along with heterocyclic nitrogen and sulfur- containing compounds. MK also shows the presence of significant amount of alkylation products. The distribution and relative abundances of PAHs in the MK are discussed in context of its petrographic grade and correlation with aqueous alteration.”
