Description
As a certified reference material (CRM), 2-[(4-amino-3-methylphenyl)sulfanyl]ethan-1-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-[(4-amino-3-methylphenyl)sulfanyl]ethan-1-ol (CAS 166818-83-3) is a high-purity analytical reference standard with the molecular formula C9H13NOS and a molecular weight of 183.27 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-[(4-amino-3-methylphenyl)sulfanyl]ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
