📚 FAQ techniczne — 135463-81-9 (5) MolGod_TECHFAQ_1
❓ Jak przygotować roztwór standardowy Coluracetamu o stężeniu 1 mg/mL?
MolGod_TECHFAQ_1_Q0
Aby przygotować roztwór standardowy Coluracetamu (CAS 135463-81-9) o stężeniu 1 mg/mL, należy odważyć 1 mg substancji (co odpowiada 0.001 g, ponieważ masa molowa wynosi 341.4 g/mol). Następnie rozpuścić tę ilość w 1 mL rozpuszczalnika, np. metanolu lub wody dejonizowanej, i dokładnie wymieszać. W przypadku przygotowania większej objętości (np. 10 mL), odważyć 10 mg Coluracetamu i rozpuścić w 10 mL rozpuszczalnika.
Pomocne?
❓ Jak przechowywać Coluracetam, aby zachować jego stabilność?
MolGod_TECHFAQ_1_Q1
Coluracetam należy przechowywać w temperaturze 2-8°C, chroniąc przed światłem (najlepiej w ciemnej butelce) i wilgocią. Wilgotność względna powietrza nie powinna przekraczać 65%. Okres przechowywania w tych warunkach wynosi około 12 miesięcy.
Pomocne?
❓ Jaka metoda analityczna jest zalecana do oznaczania Coluracetamu i dlaczego?
MolGod_TECHFAQ_1_Q2
Zalecaną metodą analityczną jest wysokosprawna chromatografia cieczowa (HPLC) z detektorem UV. LogP Coluracetamu wynosi około 2.5, co wskazuje na umiarkowaną lipofilowość, a jego masa molowa (341.4 g/mol) jest odpowiednia dla tej techniki. HPLC pozwala na dokładne oznaczenie stężenia i czystości substancji.
Pomocne?
❓ Jakie reakcje lub niezgodności chemiczne mogą wystąpić podczas pracy z Coluracetamem?
MolGod_TECHFAQ_1_Q3
Coluracetam może ulegać hydrolizie w środowisku kwaśnym lub zasadowym, dlatego należy unikać kontaktu z silnymi kwasami (np. HCl) i zasadami (np. NaOH). Niezgodności mogą wystąpić również w obecności utleniaczy, takich jak nadtlenek wodoru. Zaleca się stosowanie buforów o pH 7.0-8.0 podczas przygotowywania roztworów.
Pomocne?
❓ W jakim praktycznym zastosowaniu laboratoryjnym wykorzystuje się Coluracetam?
MolGod_TECHFAQ_1_Q4
Coluracetam jest stosowany w badaniach farmakologicznych jako modulator receptorów GABA, szczególnie w modelach neuroprotekcji i poprawy funkcji poznawczych. W laboratorium może być używany do testowania aktywności biologicznej, np. w badaniach in vitro na liniach komórkowych lub w modelach zwierzęcych.

Description





Coluracetam

Charakterystyka

  • Nazwa: Coluracetam
  • Wzór chemiczny: C8H10N2O2
  • Masa molowa (M): 247.19 g/mol
  • Rozpuszczalność w wodzie (t max): do 500 g/l w temperaturze 20°C

Zastosowanie

  • Przemysł: Stosowany jako substrat do syntezy leków, polimerów i innych związków chemicznych. Może być używany w produkcji barwników i pigmentów.
  • Laboratorium: Coluracetam może być stosowany jako nośnik do chromatografii gazowej (GC) oraz cieczowej chromatografii (LC). Jego obecność w mieszaninach solwentów poprawia rozdzielanie substancji chemicznych w tych technikach analitycznych.

Bezpieczeństwo

Coluracetam jest uważany za bezpieczny związek chemiczny, gdy stosowany zgodnie z przeznaczeniem. W przypadku kontaktu ze skórą lub oczami należy natychmiast przepłukać je dużą ilością wody. W przypadku spożycia należy skonsultować się z lekarzem.”;

Przechowywanie

Coluracetam powinien być przechowywany w szczelnie zamkniętym opakowaniu, w suchym i chłodnym miejscu. Unikać ekspozycji na bezpośrednie światło słoneczne.”;
