Eunos Technolink falls under B2. Do note you will need to check against land zoning requirements under B2 here: https://www.ura.gov.sg/Corporate/Guidelines/Development-Control/Non-Residential
B2 industrial properties are suitable for businesses with heavier manufacturing and production. For B2 industrial properties, the relevant authority such as National Environment Agency may impose a nuisance buffer of more than 50m between residential areas.
It is important that you apply for approval for the proposed use, under B2 before buying or renting a property.
You can use URA's online development register to download the Grant of Written Permission, if the premises has been granted approval for a specific use here: https://www.ura.gov.sg/maps/?service=devtreg
