P&S
Normalmente en informes técnicos/académicos/patentes, a continuación del producto/compuesto utilizado, entre paréntesis, se informa el fabricante/proveedor del mismo.
En el caso tuyo el fabricante/abastecedor de la 1-metil-2-pirrolidona es P&S, si hubieran utilizado el producto similar vendido por Aldrich hubiera aparecido "C5H9NO Aldrich o similar".
Obviamente el autor dió por sentado que el lector destinatario no necesitaría mayor aclaración. Descuidadamente da por sentado ese hecho y de paso nos complican la vida..

I think its a typo.
Discussion
Then I asked myself what can be similar to a "pa" compound. Then concluded that it is either a "pa" compound or not.
Normally one tries to buy chemicals from few purveyors.
(HCl, P&S or similar), (NaCl, P&S or similar), ... this means that "Baker", "Mallinkrodt" "Bayer", etc. also OK.
If it were "pro analisis" , which means "analytical grade", what is similar to analytical grade? Either it is analytical grade or not. If it is ppa, pure for analysis, they would have stated it.
My suggestion, consult the author and establish the context and meaning of the phrase.
barboleta3, please keep us informed as to what can be similar to a pa product, a question has been raised.
