Z-PYR-OH（CAS# 32159-21-0)
| Nā Code Risk | R22/22 - R36/37/38 – Hoʻonanea i ka maka, ka ʻōpū hanu a me ka ʻili. |
| Ka wehewehe palekana | S22 – Mai hanu i ka lepo. S24/25 – Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. S44 - S35 - Pono e hoʻolei ʻia kēia mea a me kāna ipu i kahi ala palekana. S28 – Ma hope o ka pili ʻana me ka ʻili, holoi koke me ka nui o ke kopa. S7 – Paʻa paʻa ka ipu. S4 - E haʻalele i kahi noho. |

ʻO ka Cbz-pyroglutamic acid (carbobenzoxy-L-phenylalanine) he pūhui mea ola i hoʻohana mau ʻia ma ke ʻano he pūʻulu pale amino acid i ka kemika. ʻO kāna mau mea kemika he keʻokeʻo crystalline paʻa, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka chloroform, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
ʻO kekahi o ka hoʻohana nui ʻana o CBZ-pyroglutamic acid e hana ma ke ʻano he pūʻulu pale o nā waikawa amino i ka synthesis solid-phase. Hiki iā ia ke hana i kahi ʻano amide paʻa ma ka hana ʻana me ka pūʻulu α-amino o nā waikawa amino e pale ai i nā hopena ʻē aʻe. I ka synthesizing peptides a i ʻole protein, hiki ke hoʻohana ʻia ka Cbz-pyroglutamic acid e pale pono i nā koena amino acid.
ʻO ke ʻano o ka hoʻomākaukau ʻana i ka waikawa Cbz-pyroglutamic maʻamau e hoʻopili i ka waika pyroglutamic me ka dibenzoyl carbonate (i hoʻomākaukau ʻia e ka hopena o ka dibenzoyl chloride a me ka sodium carbonate) ma lalo o nā kūlana alkaline. Pono e mālama pono ʻia ke kaʻina hana hoʻomākaukau e pale aku i nā hopena ʻaoʻao a i ʻole nā mea ʻino.
ʻIke palekana: ʻO ka Cbz-pyroglutamic acid he mea hiki ke hoʻopau ʻia, e pale i ka hoʻopili pololei ʻana me nā kumu hoʻāla. Pono e hoʻohana ʻia nā mea pale kūpono, e like me nā mīkina lima lima a me nā aniani. E hōʻalo i ka hanu ʻana i ka lepo a i ʻole ka hopena no ka mea hiki ke hoʻonāukiuki i ka ʻōnaehana hanu. I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia e hoʻopaʻa i ka ipu a mālama iā ia mai nā kumu ahi a me nā mea hiki ke ahi.
