Finding and Ordering Chemicals

(0) Set up CAS-searching bookmarklets to check chemical prices fast.

Before ordering a chemical you want:

(1) Search our TS Group Chemical Database by CAS. NB: Common reagents, salts, solvents, NMR solvents, fluorophores/chromophores/indicators, etc are Available Downstairs cheaply (full list).

(2) Search DAMARIS by CAS (all CUP groups). For bio reagents / enzymes / buffers: just ask around the Department. Can also try Wanner, Trauner/Didier, LMU Chemstore old databases.

(3) Still no hits? Vendor overviews at ChemSpider and PubChem, or go direct for:

• Chemicals: BLDPharm, Alfa (10% off), TCI Germany (10%), ChemPur (distributor for FluoroChem, 10€/delivery), Carbosynth and Clearsynth (cheap bioactives/intermediates), Fisher Scientific (distributor for Acros & Maybridge, 20%), VWR, Merck/Sigma (15%-ish); sometimes ABCR (15€/delivery) OK for unusual chemicals.
• Bioactives & bio-relateds: Biozol, Linaris, Biomol (distributor for LC Labs), Hölzel, Carbosynth, Clearsynth, Cayman.
• Basic chemicals & solvents: Carl Roth.
• Equipment: Carl Roth, NeoLab, VWR, Fisher Scientific.
• Glassware: FengTecEx (DE) & Chemglass (US).
• Isotopes: (typ. local distributors of intl suppliers such as CIL) Eurisotop, LGC, Labmix24, etc
• Small/custom suppliers: only if >100€ cheaper (shipping and tax forms). Apollo Scientific (+25€ delivery + taxes), Activate Scientific (+ delivery + taxes). Avoid Enamine, Interchim and Combi-Blocks. Use German distributors (ChemPur for FluoroChem, Fisher for Acros/Maybridge) for lower costs and no delays.
• Specialty suppliers: Strem (metals, catalysts, organometallics; 10€/delivery), Carbolutions (amino acids).

CAS-searching bookmarklets:

In your browser, create new bookmarks with the following javascripts instead of web addresses. Then, with a CAS number highlighted on any webpage, click the bookmark and it'll search that chemical supplier for the CAS number for you (test CAS: 62-53-3). (ChemPur and Linaris run .php websites, can't jump-search them yet)
