The FTIR evidence does not support a firm assignment to a specific library compound. The nearest library hit is 5-Chloro-2-hydroxybenzoic acid, but all reported library similarities are 0.000 and no direct or related literature evidence independently confirms that identity. The observed spectrum is more safely described as an oxygenated aromatic material showing hydroxyl-containing and carbonyl-associated bands, with the lower-wavenumber fingerprint region also compatible with a possible chlorinated aromatic contribution
