Cefaclor is the manufacturers name for a cephalosporin derivative. The 1H NMR spectrum is here http://assign2.chem.usyd.edu.au/thirdyear/organic/field/nmr/prb08.htm see question 3 Can't find the 13C NMR or mass spec of it. Funny how you used chromatography in your question and then refer to spectroscopic data (well it made me laugh).
