Pharmaceutical raw materials and intermediates

Pharmaceutical manufacturers source two kinds of material from us: building blocks for synthesis — benzimidazole and diphenyl intermediates, phase transfer catalysts and reagents such as sodium metal and iodine — and formulation ingredients such as sorbitol 70% solution, sodium benzoate, benzyl alcohol and menthol.

Every pharmaceutical enquiry is handled against the buyer's own specification. Tell us the assay, impurity limits, pharmacopoeia reference (IP, BP, USP or EP) and documents your quality team needs, and we will confirm what can be supplied before quoting.
