title: API for chemical information?
body: <p>I'm trying to write a python script that retrieves boiling points, melting points, molecular weight, chemical structure, and density for chemical compounds I input.</p>
  
  <p>I was looking through databases and found <a href="http://chemspipy.readthedocs.io/en/latest/" rel="nofollow noreferrer">chemspipy</a> and <a href="https://pypi.python.org/pypi/PubChemPy/1.0" rel="nofollow noreferrer">PubChemPy</a>, but neither have the ability to retrieve all of the properties I need.</p>
  
  <p>I have part of a script that uses chemspipy written, that works fine:</p>
  
  <pre><code>from chemspipy import ChemSpider
  import urllib
  
  
  cs = ChemSpider('my_token')
  
  def getImage(compound):
      c = cs.search(compound)[0]
      imgUrl = c.image_url
      urllib.request.urlretrieve(imgUrl, c.common_name + '.png')
  
  def getWeight(compound):
      c = cs.search(compound)[0]
      return(c.molecular_weight)
  </code></pre>
  
  <p>But I still need to find a way to retrieve boiling / melting points. </p>
  
  <p>(This is my first question on here, so apologies if it's in the wrong place!)</p>
