Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Formyl-1H-pyrrol-1-yl)acetic acid.
2-(2-Formyl-1H-pyrrol-1-yl)acetic acid (CAS 67451-42-7), molecular formula C7H7NO3 and molecular weight 153.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Formyl-1H-pyrrol-1-yl)acetic acid (C7H7NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2-(2-Formyl-1H-pyrrol-1-yl)acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
