Chemicals

Preset CAS-searching bookmarklets to check chemical prices fast.

(1) Search the TUDD OC Chemical Database by CAS.

(2) Still no hits? Vendor overviews at ChemSpider and PubChem, or direct to:

• Chemicals: BLDPharm, TCI, ChemPur (10€/delivery), Carbosynth and Clearsynth (bioactives/intermediates), Fisher (Acros, Maybridge), VWR, Merck/Sigma; rarely ABCR (15€/delivery).
• Bioactives & bio-relateds: Biozol, Linaris, Biomol (incl LC Labs), Hölzel, Carbosynth, Clearsynth.
• Basic chemicals & solvents: Carl Roth.
• Equipment: Carl Roth, NeoLab, VWR, Fisher Scientific.
• Glassware: FengTecEx (DE) & Chemglass (US).
• Isotopes: (local distributors for intls e.g. CIL) Eurisotop, LGC, Labmix24
• 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 these javascript addresses. Then, highlight a CAS number 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) (don't introduce spaces in the addresses):
