Ke kakali nei mākou i ka launa pū ʻana me ʻoe a me ka loaʻa ʻana o ka pilina win-win me ʻoe.E ʻoluʻolu e hōʻoluʻolu mākou iā ʻoe.E ʻoluʻolu e kelepona mai iaʻu.
1. Pehea e loaa ai na laana o 2, 4-Dichloropyrimidine CAS 3934-20-1?
Hiki iā mākou ke hāʻawi iā ʻoe i kahi laʻana manuahi no kā mākou huahana i kēia manawa, ʻo ka manawa alakaʻi he aroud 1-2 lā.
2. Hiki paha ke hana i nā lepili me kaʻu hoʻolālā pono'ī?
ʻAe, a pono ʻoe e hoʻouna mai iā mākou i kāu mau kiʻi a i ʻole nā mea hana kiʻi, a laila hiki iā ʻoe ke kiʻi i kāu makemake.
