Description
CATO manufactures 1187169-93-2 3-(5-Chloro-2-thienyl)-4-methylpyridine MFCD13152434 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.
1187169-93-2 3-(5-Chloro-2-thienyl)-4-methylpyridine MFCD13152434 (CAS 1187169-93-2), molecular formula C10H8ClNS and molecular weight 209.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 1187169-93-2 3-(5-Chloro-2-thienyl)-4-methylpyridine MFCD13152434 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
