Chemical Structure
Description
CATO supplies 2-[(5-chloro-1H-1,3-benzodiazol-2-yl)methyl]-2-ethylbutanoic acid hydrochloride (CAS 1251925-10-6), a certified reference material (molecular formula C14H17ClN2O2HCl, MW 317.21 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-[(5-chloro-1H-1,3-benzodiazol-2-yl)methyl]-2-ethylbutanoic acid hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
