Chemical Structure
Description
Structurally, 2-Amino-3-hydroxybenzoic Acid Hydrochloride 3-Hydroxyanthranilic Acid Hydrochloride 4920-81-4 H0495 (C7H13NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 195.64 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 2-Amino-3-hydroxybenzoic Acid Hydrochloride 3-Hydroxyanthranilic Acid Hydrochloride 4920-81-4 H0495 (CAS 4920-81-4), a certified reference material (molecular formula C7H13NO3HCl, MW 195.64 g/mol) for analytical method development and quality control.
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.
