621-27-2 593R721CIC 3-Propylphenol Phenol, m-propyl- (8CI) Phenol, 3-propyl- (9CI) m-Propylphenol Phenol, 3-propyl- EINECS 210-675-5 NSC 46998 UNII-593R721CIC (CAS 621-27-2) is a high-purity analytical reference standard with the molecular formula C9H18O and a molecular weight of 142.24 g/mol.
Structurally, 621-27-2 593R721CIC 3-Propylphenol Phenol, m-propyl- (8CI) Phenol, 3-propyl- (9CI) m-Propylphenol Phenol, 3-propyl- EINECS 210-675-5 NSC 46998 UNII-593R721CIC (C9H18O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 142.24 g/mol, it falls into the low-molecular-weight range.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
