strange degradant?

[vinay]

sir.i am doing some work by degradation studues of api.my parent molecular mass was 349.but by degradtion in sodium hydroxide 0.1 N i got one of my degration molecule mass is 380 please tell me the answer.
thanking you

(apologies for replying in "hijacked" thread)
perhaps 380 is due to a dimer, cluster or adduct ion of the degradant. It's hard to tell without the synthetic scheme

hi vinay
it is very difficult to predictb fom the data u have provided
but it can not be a dimer or anythnig else
as the mol wt change is very small to acoount for such a formasation
ok
and i dont know and how can mol wt in cerase of a degradation pdt
do u have any report in lit. of such an incerase i do not think so
thank you
