aromatic ester-amide conjugate with carbohydrate C–O and aliphatic chain
Vigezo vya Sampuli na Kipimo
Matokeo ya Utambulisho
29%Wigo wa FTIR unalingana na nyenzo inayochanganya utendaji wa kunukia, ester, amide, kabohidrati (aina ya pyranose) na hidrokaboni alifatiki. Ingawa maktaba ilitoa 4‑methylbenzenesulfonic acid hydrate kama mlinganisho wa karibu zaidi, bendi zilizozingatiwa hazitaawaliwa na mitetemo ya sulfonate. Badala yake, vipengele muhimu katika 1732 cm⁻¹ (kabonili ya ester), 1696 cm⁻¹ (amide I), 1067 cm⁻¹ (kunyoosha C–O kwa vitengo vya pyranose), na 1459 cm⁻¹ (kupinda kwa CH₂) zinaonyesha konjugate iliyochanganya ester/amide/kabohidrati yenye minyororo alifatiki na uingizwaji wa kunukia. Ufafanuzi wa Kina wa FTIR haukuchaguliwa kwa kazi hii, kwa hivyo sehemu hii inaonyesha matokeo ya utafutaji wa maktaba pekee na hakuna ufafanuzi wa kina wa AI uliofanywa.
Tafsiri ya kina
- Mechi bora ya maktaba: 4-methylbenzenesulfonic acid hydrate #19198
- The absence of strong sulfonic acid S–O stretching bands (expected near 1170–1150 cm⁻¹ and 1350–1300 cm⁻¹) argues against 4‑methylbenzenesulfonic acid hydrate as the sole or primary component.
- The 2175 cm⁻¹ band could represent a C–N or nitrile vibration, but the spectrum lacks other characteristic nitrile modes and does not show a prominent N–H stretch, making a purely nitrile‑containing structure less likely.
- The exact molecular identity cannot be deduced from FTIR alone; the spectrum likely reflects a mixture of structural units or a composite material.
- The assignment of the 1164 cm⁻¹ band remains ambiguous between alkyl C–H and C–O stretching, and further analysis is needed to clarify its origin.
- The 2175 cm⁻¹ feature is consistent with both a carboxylic acid combination band and a C–N stretching vibration, leaving ambiguity about the presence of a free carboxylic acid or a nitrogen‑containing functionality.
