Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.65 g/mol gives thieno[2,3-c]pyridine-7-carboxylic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
thieno[2,3-c]pyridine-7-carboxylic acid hydrochloride (CAS 2044714-45-4), molecular formula C8H5NO2SHCl and molecular weight 215.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of thieno[2,3-c]pyridine-7-carboxylic acid hydrochloride (C8H5NO2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 thieno[2,3-c]pyridine-7-carboxylic acid hydrochloride 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.
