Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-3-propoxythiophene-2-carboxylic acid.
CATO supplies 5-Chloro-3-propoxythiophene-2-carboxylic acid (CAS 1392233-78-1), a certified reference material (molecular formula C8H9ClO3S, MW 220.67 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chloro-3-propoxythiophene-2-carboxylic acid (C8H9ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Chloro-3-propoxythiophene-2-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.
