I have been in need of peptide coupling reagents, specifically PyBOP, Benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate, some peptide coupling reagents produce carcinogens as byproducts apparently, PyBOP does not, and is the particular reagent I need, I just cannot seem to find a source that ships to private individuals, most likely,  because nobody expects amateur hobbyists to be in need of advanced chemicals

I really need a source that ships to the UK, for small amounts, 20-100 grams or so, and takes paypal, solo, maestro or cheque, looked on ebay and found nothing, and cant find anything anywhere online

Anyone know of any places worh trying?

You can also look at using HBTU.  My lab uses HCTU which is a newer reagent that can supposedly give 97%+ yields and is also non-toxic.  It is not widely available however.

Unfortunately, that site does not appear to ship outside of the USA, and no methods of payment are mentioned

SWIM is UK based, and does not have a credit card unfortunately, as he is out of work at the moment.

Sigma-Aldrich do not take orders from any other than buissinesses, they are fairly notorious for it, unless you got a buissiness, then you wouldn't even stand a chance at ordering NaCl there

I am just a hobby chemist, and a lot of the large firms won't look twice at an order that isn't from a registered company.

PyBOP is not a common chemical and Sigma is one of the organic and special chemical supplier, then it is not a easy way to obtain such chemical from other supplier.
