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-(Pyridin-2-ylmethyl)-3-(o-tolyl)thiourea.
CATO supplies 1-(Pyridin-2-ylmethyl)-3-(o-tolyl)thiourea (CAS 400736-68-7), a certified reference material (molecular formula C14H15N3S, MW 257.35 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1-(Pyridin-2-ylmethyl)-3-(o-tolyl)thiourea is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 257.35 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.
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-(Pyridin-2-ylmethyl)-3-(o-tolyl)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.
