SIGMA-ALDRICH IRELAND LIMITED
SIGMA-ALDRICH IRELAND LIMITED is a Private limited company (Ltd.) registered in Ireland under IE259023, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 4 January 1997 and lists its registered address as Arklow, Ireland. 1 shareholder is on record for SIGMA-ALDRICH IRELAND LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.
