Chemical Structure

4-amino-5-chloro-2-(methoxy-<SUP>13</SUP>C, d<SUB>3</SUB>)-benzoic acid CAS 1216496-86-4 chemical structure

Description

CATO supplies 4-amino-5-chloro-2-(methoxy-<SUP>13</SUP>C, d<SUB>3</SUB>)-benzoic acid (CAS 1216496-86-4), a certified reference material (molecular formula C7[13C]H11D3ClNO3, MW 211.67 g/mol) for analytical method development and quality control.

The molecular framework of 4-amino-5-chloro-2-(methoxy-<SUP>13</SUP>C, d<SUB>3</SUB>)-benzoic acid (C7[13C]H11D3ClNO3) is characterized by deuterium isotope labeling, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-amino-5-chloro-2-(methoxy-<SUP>13</SUP>C, d<SUB>3</SUB>)-benzoic 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.
