Dimethyl 5-aminoisophthalate Dimethyl 5-aminobenzene-1,3-dicarboxylate 1,3-benzenedicarboxylic acid, 5-amino-, dimethyl ester 5-amino-isophthalic acid dimethyl ester 5-aminoisophthalic acid dimethyl ester 5-amino-dimethyl iso-phthalate 1,3-dimethyl 5-aminobenzene-1,3-dicarboxylate dimethyl-5-aminoisophthalate 5-amino-iso-phthalic acid dimethyl ester dimethyl 5-amino-isophthalate 5-amino isophthalic acid, dimethyl ester 5-amino-dimethyl isophthalate 99-27-4 (CAS 99-27-4), molecular formula C10H17NO4 and molecular weight 215.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H17NO4, Dimethyl 5-aminoisophthalate Dimethyl 5-aminobenzene-1,3-dicarboxylate 1,3-benzenedicarboxylic acid, 5-amino-, dimethyl ester 5-amino-isophthalic acid dimethyl ester 5-aminoisophthalic acid dimethyl ester 5-amino-dimethyl iso-phthalate 1,3-dimethyl 5-aminobenzene-1,3-dicarboxylate dimethyl-5-aminoisophthalate 5-amino-iso-phthalic acid dimethyl ester dimethyl 5-amino-isophthalate 5-amino isophthalic acid, dimethyl ester 5-amino-dimethyl isophthalate 99-27-4 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
