Chemical Structure

5-methyl-1H-1,3-benzodiazole-2-carbaldehyde hydrochloride CAS 1185304-18-0 chemical structure

Description

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.

5-methyl-1H-1,3-benzodiazole-2-carbaldehyde hydrochloride (CAS 1185304-18-0) is a high-purity analytical reference standard with the molecular formula C9H16N2OHCl and a molecular weight of 204.70 g/mol.

Structurally, 5-methyl-1H-1,3-benzodiazole-2-carbaldehyde hydrochloride (C9H16N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 204.70 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
