Description
As a certified reference material (CRM), 1,2-Benzenedicarboxylic Acid 1-(Carboxymethyl) Ester 1,2-Benzenedicarboxylic Acid Mono(carboxymethyl) Ester 30435-30-4 Glycolyl Hydrogen Phthalate Mono(carboxymethyl) Phthalate Phthalic Ecid monoester with Glycolic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1,2-Benzenedicarboxylic Acid 1-(Carboxymethyl) Ester 1,2-Benzenedicarboxylic Acid Mono(carboxymethyl) Ester 30435-30-4 Glycolyl Hydrogen Phthalate Mono(carboxymethyl) Phthalate Phthalic Ecid monoester with Glycolic Acid (CAS 30435-30-4), molecular formula C10H8O6 and molecular weight 224.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H8O6, 1,2-Benzenedicarboxylic Acid 1-(Carboxymethyl) Ester 1,2-Benzenedicarboxylic Acid Mono(carboxymethyl) Ester 30435-30-4 Glycolyl Hydrogen Phthalate Mono(carboxymethyl) Phthalate Phthalic Ecid monoester with Glycolic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 224.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
