Over 50 molecular species containing nitrogen have been detected in the gas phase towards various astronomical environments. A number of chemical models have tried to reproduce the observed abundances of N-bearing species in the various environments of the ISM and CSM with limited success. Recently, there has been an interest in hydroxylamine (NH$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$OH) because of its possible role in the formation of amino acids in space.\textbf{~339},~L7-L11}$\mathrm{<mrow\; data-mjx-texclass="ORD">,</mrow>}$\textbf{~129},~9910-9917} Implications of amino acid formation in space and detections of possible precursor species would have a profound impact on our pursuit of understanding the prebiotic molecular origins of life. However, hydroxylamine has yet to be detected in the gas phase in the interstellar medium. A recent gas-grain model by Garrod et al. (2008)\textbf{~682},~283-302} suggests that NH$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$OH is formed through radical recombination on grain surfaces and predicts an abundance ratio range of NH$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$OH/H$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$ between 1.2x10$\mathrm{<mrow\; data-mjx-texclass="ORD">-6</mrow>}$ - 3.5x10$\mathrm{<mrow\; data-mjx-texclass="ORD">-7</mrow>}$; thus, suggesting that NH$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$OH should be within the detectable limits of existing radio receivers. Here we present the search for hydroxylamine towards seven different sources: IRC+10216, Orion-S, Orion(KL), SgrB2(N), SgrB2(OH), W51M, and W3(IRS5) at 2mm wavelengths using archival data from the NRAO 12m telescope.\textbf{~[astro-ph]}}$\mathrm{<mrow\; data-mjx-texclass="ORD">,</mrow>}$ Hydroxylamine is not confirmed toward any region and upper limits to the total column density were determined for each source. The implications of these upper limits of NH$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$OH to both the gas phase and grain surface models will also be discussed.
