The bulb that brightens your life. 

(With a little CH₃ CH₂CH₂SH.) 

The onion. Made piquant by natural n-propyl mercaptan. One of the earliest of cultivated plants. Graven on ancient Egyptian monuments, given divine honors. Savored around the world by gourmet and gourmand. 

In the lab, too, n-propyl mercaptan can pep things up. And the other organosulfur intermediates also work some unique minor wonders. 

They can impart special characteristics: like herbicidal, fungicidal and insecticidal activity; selective solubility; reactivity; thermal stability. 

All of which presents you with some dazzling prospects for synthesis. And great versatility. Especially when Pennwalt offers 17 intermediates in commercial quantities, 12 more in pilot. 

Call us today and we’ll talk about how you might use them to improve what you’re doing … (215) 587-7000. Or write for our literature on organosulfur intermediates. Industrial Chemicals Department, Pennwalt Corporation, Three Parkway, Philadelphia, Pa. 19102.

Additional Notes: 

I was a bit confused about why there is a picture of the onion (Chiara Benedetti).
