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 2-methoxy-4-(methylsulfanyl)aniline hydrochloride.
2-methoxy-4-(methylsulfanyl)aniline hydrochloride (CAS 1657-82-5), molecular formula C8H11NOSHCl and molecular weight 205.70 g/mol, is a CATO reference standard with documented purity and traceability.
2-methoxy-4-(methylsulfanyl)aniline hydrochloride (C8H11NOSHCl) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 2-methoxy-4-(methylsulfanyl)aniline hydrochloride 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.
