Chemical Structure
Description
The occurrence of 618-47-3 Benzamide, 3-methyl- (9CI) m-Toluamide AI3-26774 EINECS 210-553-1 m-Methylbenzamide 3-Methylbenzamide NSC 2170 is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
618-47-3 Benzamide, 3-methyl- (9CI) m-Toluamide AI3-26774 EINECS 210-553-1 m-Methylbenzamide 3-Methylbenzamide NSC 2170 (CAS 618-47-3), molecular formula C8H15NO and molecular weight 141.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 618-47-3 Benzamide, 3-methyl- (9CI) m-Toluamide AI3-26774 EINECS 210-553-1 m-Methylbenzamide 3-Methylbenzamide NSC 2170 (C8H15NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
