Chemical Structure

1-(4-Chloro-2-hydroxy-5-methoxyphenyl)thiourea CAS 1820683-26-8 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 1-(4-Chloro-2-hydroxy-5-methoxyphenyl)thiourea.

1-(4-Chloro-2-hydroxy-5-methoxyphenyl)thiourea (CAS 1820683-26-8) is a high-purity analytical reference standard with the molecular formula C8H9ClN2O2S and a molecular weight of 232.69 g/mol.

1-(4-Chloro-2-hydroxy-5-methoxyphenyl)thiourea (C8H9ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 1-(4-Chloro-2-hydroxy-5-methoxyphenyl)thiourea 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.
