Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 149.58 g/mol gives 5-chloro-1H-pyrrole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-chloro-1H-pyrrole-3-carboxylic acid (CAS 79600-77-4), a certified reference material (molecular formula C5H8ClNO2, MW 149.58 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 5-chloro-1H-pyrrole-3-carboxylic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 5-chloro-1H-pyrrole-3-carboxylic 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.
