Some rare chemicals:
- P4S10
- Re2O7
- Lu2O3
Besides that, I stocked up on some common chemicals:
- 450 grams of P.A. grade KMnO4
- 400 grams of very pure S (99.98%)
- 500 grams of Mg, small granules (around 1 mm size).
The latter I will use for making H2. Fine powders are too reactive, the small granules have good reactivity and provide a nice flow of H2 when added
to 5% or so HCl.

Well, I've had a few goodies arrive recently, now that I'm able to order from Sigma Aldrich:
Acetyl chloride, 500g
Dimethyl carbonate, 500ml
Dicyclopentadiene, 100g
Acetophenone, 100ml
Phthalic anhydride, 1kg
Bromobenzene, 100ml
Bromoethane, 250ml
1-Bromobutane, 500g
Sodium amide, 25g
Hydroquinone, 100g
Catechol, 100g
Butyric anhydride, 250ml
Propionic anhydride, 250ml
Benzaldehyde, 250ml
Magnesium turnings, 100g
Butadiene sulfone, 100g
2-Chloroacetamide, 250g
Sodium anthraquinone-2-sulfonate, 100g
Thionyl chloride, 500ml
Best bit is... they accidentally sent me a litre of thionyl chloride instead of the 500ml I paid for.

That order must have cost you a fortune 
Good to see what kind of chemicals you can order. Especially thionyl chloride is a good one to have.
My P4S10 arrived last weekend. It is a free flowing yellow powder and it really smells awful!! It came in a glass bottle with plastic cap, and this
bottle in turn is in a metal can (the type in which paint usually is stored), which I had to open with a big screw driver. When I opened this metal
can, a really horrible waft of rotten egg odour escaped from it.
I did some first experiments with P4S10 and it is quite reactive. In hot water it bubbles vigorously, the bubbles being H2S. It is less flammable than
I expected. When you keep a flame at the chemical, then it does not ignite immediately. You really have to keep it in a flame for several seconds
before it starts burning. Once it burns, it keeps on burning, with a dense white smoke (P4O10) and a pungent odour (SO2).
Compared to P4S3 it is much less flammable. The latter immediately catches fire, even if conly brought in contact with a flame very briefly. P4S3 also
behaves differently when brought in contact with alkaline solutions. P4S3 gives phosphine gas, P4S10 does not give any gas at all. It dissolves,
giving phosphate and sulfide in alkaline solution.
The Re2O7 also arrived. It is a very nice greenish/yellow compound. It looks very nice.

Oooh be careful with that one. I remember reading about a case of an industrial accident where a worker inhaled P4S10 dust and ended up brain damaged.

I only know of a couple of uses but that seems like a massive amount.
Now I'm massively curious

Actually I'm mainly interested in making phthalocyanines. The 1kg was really cheap.

Well that was four separate orders but I added up the total cost including shipping and VAT and I’ve spent about £380.

what about basic equipment?
for example basic equipment for basic tasks?
there is anything such as one portable equipment that can be used to perform many tasks? eg. tool box or swiss army knife equipment
Thanks

Yes. Definitely use basic equipment for basic tasks.
For example, I am using a basic keyboard to type basic words.
But I am beginning to think I am responding to a troll.

im sorry
can you tell a bit which equipment is located on basic labs?
do you know if any of these suppliers provide samples?

What equipment are you talking about. A teaspoon is equipment. So is a mass spectromter.
How about *you* figure out what you want to do and then research the methods available and the required equipment.
Then, if you need some help with, say, configuring your setup or choosing a solvent you will be able to ask specific questions.
At the moment it is like you are saying, I want food. What equipment is there on a farm?* There is no way anyone can help you.

A few items from yet another defunct tech startup.
The phenylmethylsulfonyl fluoride is a new one for me.
Lots of amino acids and other biochemistry type stuff.
Not sure what all is in there. It was one of those, "Take everything because I need to get rid of it."situations.
I may end up selling much of it off to defray the purchase price.
This is about 1/2 of it.
Edit: Geez, make that 1/3rd.
Oxaloacetic acid?
Hepes? I sure hope that isn't contagious...

25g of methylene blue, I just needed a small amount but the 1% solution was 10 times the price of the pure powder, now I can happily make 2.5L of
indicator solution

Thanks. I'll go look for some. I was thinking about synthesizing a small for amount for some TLC experiments that I was thinking about. If I can find
at the blue box, I'm sure it will be cheaper, and hopefully not require to much purification.

Bought some 'instant cold packs' 140 gm of 'calcium ammonium nitrate' for 3usd. dissolves in water, leaving a brown sludge of chalk and some other
impurities. Purification is in order
Put that in your pipe and smoke it!

Another sigma order:
Phosphorus pentachloride, 500g
Sodium methoxide (powder), 100g
Trimethyl orthoformate, 250ml
Aniline, 1L
I decided the £33 for PCL5 was good value - cheap, even - after trying to make a small amount from the elements and having two small lab
fires in the process. The replacement extinguisher and replacement for the flask that now has an extra hole (which spewed out flaming phosphorus)
together cost more than £33.

UK EPP OTC
Although I've just got rid of my liquids prior to migrating,
I could not resist buying this
 
£6 OTC, cash, no questions asked.
The liquid is red rather than the usual brown,
it chars tissue paper but more slowly than 96% acid,
a quick density measurement indicates about 92% w/w.
I'll try to use it up in the next few weeks.

Weird that you can buy compounds for which an EPP-license is needed. I think that you had some luck. In another shop it may be that they politely ask
for a paper/proof of license and do not sell the bottle. It may even be dependent on a single person, who is not aware of the regulations and does not
read all labels on bottles which customers buy.
In the Netherlands this would be impossible. Any somewhat more risky material is behind a glass wall or behind a desk and you need to ask for it. For
some items the people behind the desk certainly will know that a license is needed and they will not sell if you do not explicitly show them the
correct papers.
Risky items also can be obtained online and then in the purchase process the company certainly has a built-in guard for accidental delivery of
licensed goods to non-licensed people. Many supply-sites for private persons (e.g. hobby-suppliers) have removed certain items completely from their
webshops, such as HNO3, H2O2 in more than 10% concentration. Fortunately, in NL, the list of licensed compounds is short, only the 7 reagents which
are regulated EU-wide.

Slightly scary one on order now- 100ml of dimethyl sulphate. I paid a little extra to get it in a Sure/Seal septum bottle because this will facilitate
safer handling.
